Butanenitrile

Butanenitrile is an organic chemical compound with the molecular formula C4H7N and CAS number 109-74-0. This nitrile compound has a molecular weight of 69.11 g/mol and is classified as a flammable liquid with significant toxicity concerns. It belongs to the family of aliphatic nitriles and is characterized by the presence of a cyano functional group (-CN) attached to a butyl chain.

Butanenitrile is a colorless liquid with a characteristic pungent odor typical of nitrile compounds. It has moderate volatility and is partially soluble in water while being miscible with most organic solvents. The compound exhibits flammable properties (Flam. Liq. 2 classification) and has a relatively low molecular weight of 69.11 g/mol, contributing to its volatility and penetration characteristics.

Butanenitrile serves primarily as an intermediate in organic synthesis and pharmaceutical manufacturing. It is commonly used in the production of various chemical compounds, including specialty chemicals, agrochemicals, and pharmaceutical intermediates. The compound's nitrile functionality makes it valuable for further chemical transformations such as hydrolysis to carboxylic acids or reduction to primary amines in industrial processes.

Butanenitrile requires careful handling due to its Acute Tox. 3 classification and flammable nature. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and appropriate respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods, away from ignition sources. Emergency eyewash stations and safety showers should be readily accessible when working with this hazardous substance.

Butanenitrile must be stored in a cool, dry, well-ventilated area away from heat sources and ignition points due to its Flam. Liq. 2 classification. Storage containers should be tightly sealed and made of compatible materials. The storage area should be equipped with appropriate fire suppression systems and spill containment measures. Keep away from incompatible materials and ensure proper labeling with GHS02 and GHS06 pictograms.

Butanenitrile exposure requires immediate action due to its Acute Tox. 3 classification. For skin contact, remove contaminated clothing and rinse affected areas with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care. Always consult safety data sheets for complete emergency procedures.

Butanenitrile disposal must comply with local and national hazardous waste regulations due to its toxicity and flammability classifications. The compound cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Incineration at high temperatures with appropriate emission controls is typically the preferred disposal method. Always consult with certified waste management companies and follow applicable environmental regulations for proper disposal.

Butanenitrile is classified under ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport regulations compliance. Packages must bear appropriate hazard labels including GHS02 and GHS06 pictograms with 'Danger' signal word. Transportation requires proper documentation, trained personnel, and compatible packaging materials. Vehicles must be equipped with appropriate safety equipment and emergency response information for Class 3 dangerous goods.

Butanenitrile is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification obligations. The compound is not currently listed as a SVHC (Substance of Very High Concern) but must comply with standard chemical safety assessments. Its Acute Tox. 3 and Flam. Liq. 2 classifications trigger specific labeling, safety data sheet, and handling requirements under European chemical legislation.
