2,2,2-trichloroacetonitrile

2,2,2-trichloroacetonitrile is an organochlorine compound with the molecular formula C2Cl3N and CAS number 545-06-2. This chemical features three chlorine atoms attached to the methyl carbon of acetonitrile, creating a highly chlorinated nitrile compound with a molecular weight of 144.38 g/mol. It is classified as a highly toxic substance requiring careful handling due to its acute toxicity properties and environmental hazards.

2,2,2-trichloroacetonitrile is typically a colorless to pale yellow liquid at room temperature with a characteristic sharp, pungent odor. The compound has limited solubility in water but is generally soluble in organic solvents such as alcohols and chlorinated solvents. Its high chlorine content contributes to its density and chemical stability, while the nitrile functional group influences its reactivity and polarity characteristics.

2,2,2-trichloroacetonitrile serves primarily as a chemical intermediate in pharmaceutical and agrochemical synthesis. It is utilized in the production of various organic compounds where the trichloromethyl group needs to be introduced into molecular structures. The compound also finds applications in specialized chemical research and as a building block for creating more complex chlorinated organic molecules in industrial chemical processes.

2,2,2-trichloroacetonitrile requires strict safety measures due to its Acute Tox. 3 classification. Personnel must wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection in well-ventilated areas. Work should be conducted in fume hoods to prevent inhalation exposure. Emergency eyewash stations and safety showers should be readily accessible, and all handling procedures must follow established chemical safety protocols.

2,2,2-trichloroacetonitrile must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. The compound should be kept in tightly sealed, chemically compatible containers, preferably in a designated hazardous chemical storage area. Storage areas must be equipped with appropriate containment measures and should be separated from incompatible materials such as strong bases and reducing agents to prevent dangerous reactions.

Immediate action is required upon contact with 2,2,2-trichloroacetonitrile due to its high toxicity. For skin contact, remove contaminated clothing and rinse the affected area with copious amounts of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical assistance.

2,2,2-trichloroacetonitrile must be disposed of as hazardous waste through licensed waste disposal companies in accordance with local and EU regulations. The compound cannot be disposed of down drains or in regular waste streams due to its toxicity and environmental impact classification (Aquatic Chronic 2). Proper documentation and waste tracking procedures must be followed, and disposal methods typically involve high-temperature incineration at specialized facilities.

2,2,2-trichloroacetonitrile is classified under ADR as Class 6.1 (Toxic substances), Packing Group I, indicating high toxicity requiring stringent transport regulations. Shipments must use UN-approved packaging and be properly labeled with appropriate hazard placards and documentation. Transport vehicles must comply with ADR requirements for toxic substances, and drivers need specialized training for handling dangerous goods of this classification level.

2,2,2-trichloroacetonitrile is subject to comprehensive EU chemical regulations including REACH registration requirements and CLP classification obligations. The compound's GHS06 and GHS09 pictograms indicate mandatory hazard communication requirements. While not currently listed as an SVHC substance, it falls under strict handling and reporting requirements due to its acute toxicity classification and must comply with occupational exposure limits and environmental protection standards.

2,2,2-trichloroacetonitrile is available through OYSI, a specialized European distributor of technical chemicals serving industrial and research customers across Europe. OYSI provides this compound with full regulatory compliance documentation and technical support. Due to the substance's classification as Acute Tox. 3 and transport restrictions, purchases require proper handling capabilities and may be subject to customer qualification requirements and regulatory documentation.
