Methyl carbonochloridate

Methyl carbonochloridate is an organochlorine compound with the molecular formula C2H3ClO2 and CAS number 79-22-1. This chemical substance has a molecular weight of 94.5 g/mol and belongs to the family of chloroformate esters. It is classified as a highly hazardous material due to its flammable, toxic, and corrosive properties, requiring strict safety protocols during handling and storage in industrial applications.

Methyl carbonochloridate is a colorless to pale yellow liquid at room temperature with a pungent, irritating odor. It has a molecular weight of 94.5 g/mol and is highly reactive with water, undergoing hydrolysis to form methanol, carbon dioxide, and hydrogen chloride. The compound is soluble in organic solvents but reacts vigorously with moisture, making it sensitive to atmospheric humidity.

Methyl carbonochloridate is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a reagent for introducing methoxycarbonyl groups into organic molecules and is employed in the production of carbamates, pharmaceuticals, and agrochemicals. Due to its reactive nature, it is exclusively used in controlled industrial environments by trained professionals following strict safety protocols.

Methyl carbonochloridate requires extreme caution due to its corrosive and toxic properties. Personnel must wear full chemical-resistant protective equipment including acid-resistant gloves, chemical goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods, away from ignition sources due to its flammable nature. Emergency shower and eyewash stations must be readily accessible during handling operations.

Methyl carbonochloridate must be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Storage areas should be equipped with appropriate containment systems and maintained below 25°C. The substance must be kept away from water, alcohols, amines, and strong bases, as these can cause violent reactions or decomposition.

Immediate decontamination is critical following exposure to methyl carbonochloridate. For skin contact, remove contaminated clothing and flush affected areas with copious amounts of water for at least 15 minutes. In case of eye contact, irrigate eyes immediately with clean water for 15-20 minutes. If inhaled, move the person to fresh air immediately. Seek immediate medical attention for all exposure routes due to the substance's high toxicity.

Methyl carbonochloridate waste must be disposed of through licensed hazardous waste disposal facilities in accordance with local and European waste regulations. The substance cannot be disposed of through regular waste streams due to its toxic and corrosive properties. Small quantities should be neutralized by trained personnel using appropriate chemical treatment methods before disposal, while larger amounts require professional hazardous waste management services.

Methyl carbonochloridate is classified under ADR Class 6.1 (Toxic substances) with Packing Group I, indicating high toxicity. Transportation requires specialized packaging meeting UN specifications and proper hazard labeling with GHS02, GHS06, and GHS05 pictograms. Only certified carriers trained in hazardous material transport are authorized to handle shipments, and all transport documentation must comply with European dangerous goods regulations.

Methyl carbonochloridate is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification standards. The substance carries multiple hazard classifications including Flam. Liq. 2, Acute Tox. 2, and Skin Corr. 1B, requiring strict compliance with occupational safety standards. While not currently listed as an SVHC, its high toxicity profile means it may be subject to additional regulatory restrictions and monitoring requirements.

Methyl carbonochloridate is available through specialized chemical distributors like OYSI, which supplies industrial chemicals across Europe. Due to its hazardous nature and regulatory requirements, purchases are restricted to qualified industrial users with appropriate handling capabilities. Buyers must demonstrate proper safety protocols, storage facilities, and regulatory compliance before procurement.
