2-chloroacetaldehyde

2-chloroacetaldehyde is a chlorinated organic compound with the molecular formula C2H3ClO and CAS number 107-20-0. This chemical substance has a molecular weight of 78.5 g/mol and belongs to the aldehyde family. It is classified as a highly hazardous substance with multiple danger classifications including carcinogenic properties (Carc. 2), acute toxicity, skin corrosion, and aquatic toxicity. The compound requires careful handling due to its significant health and environmental risks.

2-chloroacetaldehyde is typically a colorless to pale yellow liquid at room temperature with a pungent, acrid odor characteristic of aldehydes. The compound is highly reactive due to both its aldehyde functional group and the presence of chlorine. It is miscible with water and most organic solvents, making it highly mobile in various environments. The substance is volatile and can easily evaporate, contributing to its inhalation hazard potential.

2-chloroacetaldehyde is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a building block for producing various chemicals, including pharmaceuticals, agrochemicals, and specialty organic compounds. The compound is also utilized in research laboratories for synthetic chemistry applications. Due to its high toxicity and carcinogenic properties, its use is restricted to professional industrial applications with appropriate safety measures and regulatory compliance.

2-chloroacetaldehyde requires maximum protection during handling due to its extreme hazards. Essential PPE includes full-face respirators with appropriate cartridges, chemical-resistant gloves (nitrile or neoprene), complete body protection suits, and safety goggles. Work must be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion completely. Emergency eyewash stations and safety showers must be readily accessible. Only trained personnel should handle this substance.

2-chloroacetaldehyde must be stored in tightly sealed, chemically compatible containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Storage areas should be equipped with appropriate containment systems and maintained at controlled temperatures. Keep away from incompatible materials such as strong bases, oxidizing agents, and metals. Access should be restricted to authorized personnel only, with proper inventory tracking and emergency response procedures in place.

Immediate action is critical for any exposure to 2-chloroacetaldehyde. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, rinse continuously with water for at least 15 minutes. In all cases, seek immediate medical attention and inform healthcare providers of the specific chemical involved. Never induce vomiting if ingested.

2-chloroacetaldehyde disposal must comply with local, national, and EU hazardous waste regulations due to its classification as dangerous waste. The substance requires treatment at authorized hazardous waste facilities equipped to handle toxic and potentially carcinogenic materials. Incineration at high temperatures in specialized facilities is typically the preferred disposal method. Never dispose of through regular waste streams, sewers, or soil. Contact licensed hazardous waste contractors for proper collection and disposal procedures.

2-chloroacetaldehyde is classified under ADR Class 6.1 (Toxic substances) Packing Group I, indicating maximum transport restrictions due to its high toxicity. Transportation requires UN-approved packaging, proper labeling with GHS pictogrammes (GHS05, GHS06, GHS08, GHS09), and transport documents specifying the hazard class. Only certified carriers trained in dangerous goods transport can handle shipments. Emergency response information and appropriate safety equipment must accompany all shipments according to ADR regulations.

2-chloroacetaldehyde is subject to extensive European regulations under REACH and CLP classifications. Its Carc. 2 classification means it requires authorization for many uses and is subject to strict occupational exposure limits. The substance falls under various industrial emissions directives and workplace safety regulations. Companies using this chemical must maintain detailed safety data sheets, conduct risk assessments, and implement appropriate risk management measures. Regular monitoring and reporting may be required depending on usage quantities.
