2-nitropropane

2-nitropropane is an organic chemical compound with the molecular formula C3H7NO2 and CAS number 79-46-9. It belongs to the nitroalkane family, featuring a nitro group (-NO2) attached to the central carbon of a propane chain. With a molecular weight of 89.09 g/mol, this substance is classified as a flammable liquid and carcinogen category 1B, requiring careful handling due to its significant health and safety hazards.

2-nitropropane is a colorless liquid at room temperature with a characteristic sweet, fruity odor. It has moderate solubility in water and is miscible with most organic solvents including alcohols and ethers. The compound has a boiling point of approximately 120°C and a flash point around 24°C, making it a flammable liquid. Its density is higher than water at about 0.99 g/cm³.

2-nitropropane is primarily used as a solvent in industrial applications, particularly for cellulose compounds, resins, and dyes. It serves as an intermediate in organic synthesis and pharmaceutical manufacturing. The compound is also utilized in rocket propellants and as a fuel additive. Additionally, it finds applications in the production of specialty chemicals and as a reaction medium in various chemical processes requiring aprotic solvents.

2-nitropropane requires strict safety measures due to its carcinogenic and flammable properties. Use appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection. Work in well-ventilated areas or under fume hoods to prevent inhalation. Eliminate ignition sources and use explosion-proof equipment. Ground all containers during transfer operations and avoid skin contact. Regular health monitoring is essential for workers with potential exposure.

2-nitropropane must be stored in cool, dry, well-ventilated areas away from heat sources and ignition points. Keep containers tightly sealed in original packaging, preferably in fireproof cabinets designed for flammable liquids. Store away from incompatible materials such as strong oxidizers, acids, and bases. Maintain storage temperature below 25°C and implement proper fire suppression systems. Regular inspection of containers for leaks is mandatory.

Immediate action is crucial upon contact with 2-nitropropane. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. In case of eye contact, flush with clean water for 15 minutes and remove contact lenses if present. If ingested, do not induce vomiting and seek immediate medical care. Always consult emergency services for serious exposures.

2-nitropropane disposal must comply with local and national hazardous waste regulations due to its carcinogenic properties. The substance cannot be disposed of in regular waste streams and requires specialized treatment at licensed hazardous waste facilities. Incineration at high temperatures with appropriate emission controls is the preferred method. Small quantities should be collected in appropriate containers and handed over to certified waste management companies. Never discharge into sewers or environment.

2-nitropropane is classified under ADR as Class 3 (flammable liquids), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with proper labeling including GHS02, GHS07, and GHS08 pictograms and 'Danger' signal word. Transport vehicles must carry appropriate emergency equipment and documentation. Drivers require ADR certification for dangerous goods transport. Ensure proper segregation from incompatible materials during shipping.

2-nitropropane is subject to extensive regulatory oversight under REACH, CLP, and occupational safety regulations due to its carcinogenic classification (Category 1B). It requires safety data sheets and proper hazard communication. Workplace exposure limits are strictly regulated, and employers must implement comprehensive risk assessments. The substance may face restrictions in certain applications and requires authorization for specific uses under REACH Annex XIV provisions.

2-nitropropane is available through specialized chemical distributors in Europe, including OYSI, which supplies high-quality industrial chemicals across European markets. Due to its hazardous classification, purchase requires proper documentation, safety assessments, and compliance with regulatory requirements. Suppliers must provide comprehensive safety data sheets and ensure appropriate packaging.
