2-methylpropyl nitrite

2-methylpropyl nitrite is an organic chemical compound with the molecular formula C4H9NO2 and CAS number 542-56-3. It belongs to the alkyl nitrite family and has a molecular weight of 103.12 g/mol. This substance is classified as a flammable liquid with significant health hazards including carcinogenic and mutagenic properties. It requires careful handling due to its acute toxicity and is regulated under various safety classifications including GHS pictograms for flammability, health hazards, and irritation.

2-methylpropyl nitrite is a volatile organic liquid at room temperature with characteristic properties typical of alkyl nitrites. As an ester of nitrous acid, it exhibits flammable properties classified under Flam. Liq. 2 category. The compound has a molecular mass of 103.12 g/mol and contains four carbon atoms in its branched structure. Its volatile nature and organic composition make it soluble in organic solvents while being relatively unstable, requiring controlled storage conditions.

2-methylpropyl nitrite is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing processes. Its nitrite functional group makes it valuable in specific chemical reactions where nitrosation or nitrite transfer is required. Due to its hazardous classification including carcinogenic properties, its industrial applications are strictly controlled and limited to professional settings with appropriate safety measures. The compound requires specialized handling procedures and is typically used only in well-ventilated laboratory or industrial environments.

2-methylpropyl nitrite requires strict safety protocols due to its Danger signal word and multiple hazard classifications. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas. Given its flammable nature (Flam. Liq. 2) and acute toxicity, eliminate all ignition sources and avoid skin contact or inhalation. Work in fume hoods when possible, and ensure emergency eyewash and shower facilities are accessible. Only trained personnel should handle this carcinogenic substance.

2-methylpropyl nitrite must be stored in a cool, dry, well-ventilated area away from heat sources and ignition points due to its Flam. Liq. 2 classification. Use appropriate chemical storage cabinets designed for flammable liquids with secondary containment. Keep containers tightly sealed to prevent evaporation and degradation. Store away from incompatible materials including strong oxidizers and reducing agents. Maintain storage temperature below recommended limits and ensure proper labeling with GHS02, GHS07, and GHS08 pictograms for safety identification.

Immediate action is required upon contact with 2-methylpropyl nitrite due to its acute toxicity classification. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for 15 minutes while holding eyelids open. If ingested, do not induce vomiting and seek immediate medical attention. Always inform medical personnel about the substance's carcinogenic and mutagenic properties.

2-methylpropyl nitrite must be disposed of through licensed hazardous waste disposal facilities due to its carcinogenic classification and flammable properties. Never dispose of this substance down drains or in regular waste streams. Container disposal requires special handling as empty containers may retain hazardous residues. Follow local and European waste regulations (EWC codes) for organic chemical waste. Incineration must be performed at authorized facilities capable of handling carcinogenic materials with appropriate emission controls and temperature requirements.

2-methylpropyl nitrite is classified under ADR Class 3 (Flammable Liquids), Packing Group II, requiring specialized transport procedures. Packages must comply with UN packaging standards for dangerous goods and bear proper hazard labels including flammable liquid markings. Transport vehicles need appropriate placarding and emergency equipment. Drivers require ADR certification for Class 3 substances. Documentation must include proper shipping names, hazard classifications, and emergency response information. Only authorized carriers experienced in dangerous goods transport should handle shipments of this substance.

2-methylpropyl nitrite is subject to extensive European chemical regulations including REACH registration requirements and CLP classification obligations. Its Carc. 1B and Muta. 2 classifications trigger strict workplace exposure limits and reporting requirements. While not currently listed as an SVHC, its carcinogenic properties may subject it to authorization procedures. Industrial users must implement risk management measures and provide safety data sheets. Transport requires ADR compliance, and occupational exposure is regulated under health and safety directives requiring medical surveillance programs.

2-methylpropyl nitrite is available through specialized European chemical distributors like OYSI, which supplies industrial chemicals across Europe. Due to its hazardous classification and regulatory requirements, this substance is only supplied to qualified industrial customers with appropriate handling capabilities. Purchasers must demonstrate legitimate industrial use and compliance with safety regulations.
