Cyclopentyl carbonochloridate

Cyclopentyl carbonochloridate is an organic chemical compound with the molecular formula C6H9ClO2 and CAS number 50715-28-1. This chloroformate derivative has a molecular weight of 148.59 g/mol and belongs to the family of carbonyl chlorides. It is classified as a hazardous substance with multiple danger categories including flammability, acute toxicity, and corrosive properties, requiring careful handling in industrial applications.

Cyclopentyl carbonochloridate is a liquid organic compound at room temperature with the molecular formula C6H9ClO2. As a chloroformate ester, it typically exhibits high reactivity with water and alcohols, forming hydrochloric acid upon hydrolysis. The compound is flammable (category 3) and likely has a pungent odor characteristic of chloroformates. Its exact physical properties such as boiling point and density require consultation of detailed technical datasheets.

Cyclopentyl carbonochloridate serves as an important intermediate in organic synthesis and pharmaceutical manufacturing. It is primarily used as a reagent for introducing cyclopentyl carbamate protecting groups in peptide synthesis and for preparing cyclopentyl esters of carboxylic acids. The compound finds applications in fine chemical synthesis, pharmaceutical research, and as a building block for more complex organic molecules in specialized chemical processes.

Cyclopentyl carbonochloridate requires strict safety protocols due to its acute toxicity and corrosive nature. Essential PPE includes chemical-resistant gloves, safety goggles or face shield, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing. Keep away from heat sources and ignition due to its flammable properties (category 3).

Cyclopentyl carbonochloridate must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition. Keep containers away from moisture as the compound reacts with water to form corrosive hydrochloric acid. Store separately from bases, alcohols, and amines to prevent dangerous reactions. Ensure storage areas have appropriate spill containment and are accessible only to trained personnel with proper safety equipment.

Immediate action is critical due to the compound's corrosive and toxic properties. For skin contact, immediately remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. For eye contact, flush immediately with water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheets for complete emergency procedures.

Cyclopentyl carbonochloridate disposal must comply with local and national hazardous waste regulations as it is classified as toxic and corrosive waste. The compound cannot be disposed of in regular waste streams or sewers. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require neutralization under controlled conditions by trained personnel. Always consult local environmental authorities for specific disposal requirements and approved facilities.

Cyclopentyl carbonochloridate is classified under ADR as Class 6.1 (Toxic substances), Packing Group II, indicating significant transport restrictions. Transportation requires appropriate UN-specification packaging, proper labeling with GHS pictograms (GHS02, GHS06, GHS08, GHS05), and accompanying transport documents. Only certified carriers experienced in hazardous materials transport should handle shipments. Vehicles must carry appropriate emergency equipment and drivers must have hazardous materials training certification.

Cyclopentyl carbonochloridate is subject to multiple regulatory frameworks including REACH registration requirements for European markets and CLP classification as a dangerous substance. It is not currently listed as an SVHC (Substance of Very High Concern) but falls under strict handling, storage, and transport regulations due to its hazard classification. Users must comply with occupational safety regulations, environmental protection laws, and chemical safety assessments before use.
