Butyl nitrite

Butyl nitrite is an organic chemical compound with the molecular formula C4H9NO2 and CAS number 544-16-1. 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 and acutely toxic compound, requiring careful handling due to its hazardous properties. It appears as a pale yellow liquid with a characteristic fruity odor and is commonly used in various industrial applications.

Butyl nitrite is a pale yellow to colorless liquid at room temperature with a distinctive sweet, fruity odor. It has a molecular weight of 103.12 g/mol and is slightly soluble in water but miscible with organic solvents like alcohol and ether. The compound is volatile and decomposes readily when exposed to light, heat, or alkaline conditions. It has a relatively low boiling point and high vapor pressure, making it easily evaporable at ambient temperatures.

Butyl nitrite is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a nitrosating agent in chemical reactions and is employed in the production of various organic compounds. In industrial applications, it functions as a solvent and reagent in specialized chemical processes. The compound is also utilized in research laboratories for analytical purposes and as a precursor for synthesizing other nitrite esters and related chemical derivatives.

Butyl nitrite requires careful handling due to its flammable and toxic nature. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing when working with this substance. Ensure adequate ventilation to prevent vapor accumulation and avoid sources of ignition. Work in a well-ventilated area or under a fume hood, and never eat, drink, or smoke while handling. Keep containers tightly closed and use only non-sparking tools during manipulation.

Butyl nitrite must be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and ignition sources. Keep containers tightly sealed in their original packaging and store below 25°C to prevent decomposition. The substance should be separated from oxidizing agents, acids, and alkaline materials due to incompatibility risks. Store in a designated flammable liquids cabinet and ensure adequate fire suppression systems are available in the storage area.

Butyl nitrite exposure requires immediate action due to its acute toxicity. In case of skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, flush with clean water for at least 15 minutes while holding eyelids open. If ingested, do not induce vomiting and seek immediate medical assistance while providing safety data sheet information to healthcare providers.

Butyl nitrite disposal must comply with local and national hazardous waste regulations due to its classification as dangerous goods. The substance cannot be disposed of in regular waste streams and requires specialized treatment at authorized hazardous waste facilities. Collect waste in compatible, labeled containers and arrange collection through licensed waste management companies. Never pour down drains or sewers, and avoid incineration without proper emission controls due to toxic decomposition products formation.

Butyl nitrite is classified as dangerous goods under ADR regulations with UN class 3 (flammable liquids) and packing group II. Transportation requires appropriate packaging, labeling with GHS02 and GHS06 pictograms, and proper shipping documentation including safety data sheets. Vehicles must comply with ADR requirements for flammable liquids transport, including proper ventilation and fire safety equipment. Only trained personnel should handle transportation, and emergency response procedures must be available during transit.

Butyl nitrite is subject to various European regulations including REACH registration requirements and CLP classification standards. The substance is classified under the Globally Harmonized System with 'Danger' signal word and specific hazard statements for flammability and acute toxicity. While not currently listed as a Substance of Very High Concern (SVHC), it requires compliance with occupational health and safety regulations, transportation rules, and waste management directives across EU member states.
