Ethyl Nitrate requires careful safety and regulatory review in China because its hazards, transport status, and permitted handling conditions depend on verified classification and use. A supplier’s safety data sheet is a starting point, not a substitute for checking current Chinese requirements. The State Council’s Regulations on the Safety Management of Hazardous Chemicals and the Ministry of Emergency Management’s relevant catalogues provide important reference points. Applicability should be confirmed against the substance’s identity, concentration, packaging, and intended activity. Small details matter.
For a wider perspective, UNEP’s Global Chemicals Outlook II (2019) highlights persistent gaps in chemicals management capacity, while the OECD’s Environmental Performance Reviews: China (2019) discusses the country’s environmental governance and regulatory context. Neither report classifies Ethyl Nitrate specifically; that distinction matters. Importers, laboratories, and industrial users should verify current Chinese rules, obtain compliant Chinese-language hazard information, and consult qualified safety and regulatory professionals before handling or shipping the substance. Clear records, accurate labels, and suitable emergency planning are practical safeguards, not paperwork for its own sake. Requirements can change, and public summaries may omit details. A cautious review is still better than an assumption.
Ethyl Nitrate Safety and Regulatory Requirements in China
Ethyl nitrate is identified by CAS 625-58-1 and has a molecular weight of 91.07 g/mol. These two values should appear consistently across the SDS, container label, purchase record, and laboratory inventory. A small transcription error can affect hazard screening. Verify the substance identity before handling it.
Ethyl nitrate is a volatile, flammable nitrate ester. It may decompose dangerously when exposed to heat, flames, impact, or incompatible materials. Store it only in a controlled, cool, well-ventilated area, away from ignition sources and reducing agents. Use suitable chemical-resistant gloves, eye protection, and local exhaust ventilation. Do not rely on odor as a warning. It is unreliable.
In China, compliance normally depends on the substance classification, concentration, quantity, intended use, packaging, and transport route. Safety teams should check applicable national standards, chemical registration obligations, workplace controls, and hazardous-goods transport requirements. The SDS should be prepared in Chinese and reflect current classification data. Emergency planning also matters, including spill isolation, fire response, and exposure treatment. Records should identify responsible personnel and inspection dates. A label that looks complete may still omit storage limits or incompatibilities. That deserves review. Because requirements can change, qualified Chinese regulatory and occupational-safety professionals should confirm the final controls before procurement, storage, or use.
| Preferred chemical name | Ethyl nitrate |
|---|---|
| Other name | Nitric acid, ethyl ester |
| CAS Registry Number | 625-58-1 |
| Molecular formula | C2H5NO3 |
| Molecular weight | 91.07 g/mol |
| Chemical structure | CH3CH2ONO2 (ethyl ester of nitric acid) |
| Primary hazard concern | Ethyl nitrate is an energetic nitrate ester and may present a severe explosion and fire hazard. Do not assume that an ordinary flammable-liquid classification alone describes its hazards. |
| Hazard classification and label | Use the classification, signal word, hazard statements, precautionary statements, and pictograms established for the specific product in its current Chinese-compliant Safety Data Sheet (SDS) and label. Do not assign a GHS category from the chemical name alone. |
| China hazardous-chemical status | Before import, manufacture, sale, use, or storage, verify the exact substance and CAS number against the current official Chinese hazardous-chemical catalogue and applicable updates. Confirm any licensing, registration, or other obligations with the competent local authorities. |
| Explosive-material controls | Because of its energetic properties, obtain a substance-specific regulatory assessment before handling or placing it into commerce. Do not assume that inclusion in, or exemption from, an explosives-related control regime can be determined from the product name alone. |
| Workplace safety requirements | Apply China’s current Work Safety Law and the Regulations on the Safety Management of Hazardous Chemicals where applicable. Conduct a documented risk assessment, restrict access, train workers, and maintain suitable emergency procedures. |
| SDS and workplace communication | Obtain a current Chinese-language SDS and compliant hazard label from a qualified supplier. Ensure the SDS identifies the substance, hazards, handling and storage precautions, exposure controls, emergency measures, and applicable transport information. |
| Storage precautions | Store only under conditions approved for the specific material and quantity. Keep away from heat, ignition sources, contamination, and incompatible materials; use appropriate access controls and follow the SDS and site-specific safety assessment. Do not establish storage limits without a regulatory and engineering review. |
| Handling precautions | Limit handling to trained, authorized personnel using suitable equipment and protective measures specified by the SDS and risk assessment. Avoid unnecessary handling and prevent contamination or uncontrolled heating. |
| Transport classification | Do not infer a UN number, dangerous-goods class, packing group, or permitted transport method from this reference table. Confirm the current classification for the actual formulation and quantity with the supplier’s SDS and the applicable Chinese transport requirements before shipment. |
| Emergency response | In the event of suspected fire, decomposition, or loss of containment, raise the alarm, withdraw people from the affected area, and contact trained emergency responders. Response and firefighting decisions should be made by competent personnel using the substance-specific emergency information. |
| Regulatory verification note | This table is a general reference, not a legal determination or substitute for a current SDS. Chinese catalogue status, permit requirements, classification, and transport controls may depend on the substance identity, formulation, quantity, activity, and rules in force at the time of handling. |
It requires suitable facilities, trained workers, risk controls, and safety records. Requirements can vary by site and activity.
Classification affects labels, storage decisions, and workplace precautions. Use verified physical data, and keep the safety data sheet consistent with container markings.
No. Check current catalogues, permits, and transport requirements too. Paperwork can look complete while daily controls remain weak.
Verify the chemical identity, CAS number, purity, concentration, and intended use. Do not rely on a supplier description alone.
Review measured air levels, task duration, release points, and worker proximity. Include sampling, cleaning, and maintenance. Short tasks matter.
Prioritize closed systems, ventilation, compatible equipment, and ignition-source control. Match protective equipment to the safety data sheet and risk assessment.
Use marked, access-controlled areas with suitable ventilation and inspected containers. Keep emergency contacts and evacuation routes visible. Do not improvise cleanup.
Inspect ventilation and containers each shift, test alarms, and review drills. A working alarm is not enough; unclear roles need attention.
Ethyl Nitrate is a volatile nitrate ester identified by CAS 625-58-1, with a molecular weight of 91.07 g/mol and a boiling point of approximately 87°C. Its principal safety concern is the potential for explosive decomposition, particularly when exposed to heat, ignition sources, contamination, or unsuitable storage conditions. Safe handling therefore requires strict control of temperature, ventilation, ignition sources, and incompatible materials, supported by documented risk assessments and trained personnel.
In China, the management of Ethyl Nitrate should be aligned with the hazardous-chemical classification framework established under State Council Decree 591 and GB 30000.7-2013. Workplace exposure and occupational protection should be evaluated with reference to GBZ 2.1-2019, while storage arrangements should follow the principles of GB 15603-2022. Organizations should maintain clear labeling, access controls, inspection procedures, emergency equipment, and incident response plans to reduce risks to workers, facilities, and the surrounding environment.
