Cyclopentyl carbonochloridate

Cyclopentyl carbonochloridate is an organic chemical compound with the molecular formula C6H9ClO2 and CAS number 50715-28-1. This chloroformate ester has a molecular weight of 148.59 g/mol and belongs to the family of carbonochloridates. It is classified as a hazardous substance with multiple danger classifications including flammable liquid, acute toxicity, eye damage, and skin sensitization properties, requiring careful handling in industrial applications.

Cyclopentyl carbonochloridate is typically a liquid at room temperature with characteristic properties of chloroformate esters. As an organic compound containing chlorine, it likely has a pungent odor and is reactive with water and alcohols. The substance has a molecular weight of 148.59 g/mol and formula C6H9ClO2. Its flammable nature (Flam. Liq. 3) indicates moderate fire hazard, and specific physical properties should be verified through technical data sheets.

Cyclopentyl carbonochloridate is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. As a chloroformate ester, it serves as a reagent for introducing cyclopentyl groups into molecules and for forming carbamates, carbonates, and other derivatives. It is commonly employed in research laboratories and industrial processes requiring selective functionalization reactions, particularly in the synthesis of complex organic compounds and active pharmaceutical ingredients.

Cyclopentyl carbonochloridate requires strict safety measures due to its multiple hazard classifications. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume hoods to avoid inhalation. Given its acute toxicity, eye damage potential, and skin sensitization properties, minimize exposure and ensure emergency equipment is readily available.

Cyclopentyl carbonochloridate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and ignition sources due to its flammable properties. Keep containers away from moisture, as chloroformates react with water. Store separately from incompatible materials such as alcohols, amines, and strong bases. Ensure storage areas comply with local regulations for flammable and toxic substances, and maintain appropriate temperature control.

Immediate action is crucial due to the substance's corrosive and toxic properties. For skin contact, remove contaminated clothing and flush affected area with plenty of water for at least 15 minutes. For eye contact, rinse immediately with water for at least 15 minutes and seek medical attention urgently due to eye damage potential. If inhaled, move to fresh air immediately. In all cases of exposure, seek medical attention promptly and provide safety data sheet information to medical personnel.

Cyclopentyl carbonochloridate must be disposed of as hazardous waste in accordance with local, national, and international regulations. Contact licensed hazardous waste disposal companies for proper collection and treatment. Never dispose of this substance down drains or into the environment due to its toxic properties. Small quantities may be neutralized carefully by trained personnel following established procedures, but professional disposal services are recommended for safety and regulatory compliance.

Cyclopentyl carbonochloridate is classified under ADR as Class 6.1 (Toxic substances), Packing Group II, indicating significant transport restrictions. Shipments must comply with dangerous goods regulations including proper packaging, labeling, and documentation. Only certified dangerous goods transporters should handle shipments. Packages must display appropriate hazard labels and shipping names. Emergency response information must accompany shipments, and drivers require dangerous goods training certification.

Cyclopentyl carbonochloridate is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification for hazard communication. While not currently listed as an SVHC (Substance of Very High Concern), its hazardous properties require compliance with occupational safety regulations, transport laws (ADR), and environmental protection measures. Users must maintain safety data sheets, implement risk assessments, and follow workplace exposure limits where established.

Cyclopentyl carbonochloridate is available through specialized chemical distributors in Europe, including OYSI, which supplies high-quality chemical products across European markets. As a controlled hazardous substance, purchases typically require proper documentation, safety qualifications, and intended use declarations.
