Application Areas

Organic synthesis intermediates: mainly used for synthesizing organic compounds containing cyclopentene structures, such as drugs, pesticides, and fine chemicals.
Chemical research: used as a laboratory reagent to study the reaction mechanism of cyclic compounds

Storage conditions

Environment and packaging: Store in a cool, ventilated warehouse, keep the container sealed, and keep away from sources of fire and oxidants. It is recommended to use explosion-proof storage facilities to avoid static electricity accumulation.
Temperature control: Low temperature and dry environment, avoid high temperature or light exposure

Safety precautions

Health hazards:
Toxicity: May release toxic chloride smoke, which is irritating to the respiratory tract.
Explosion risk: Unstable at room temperature, may decompose and explode.
Protective measures:
Respiratory protection: Wear self-contained breathing apparatus in high concentration environments.
Skin/Eye Protection: Wear chemical resistant gloves, goggles, and protective clothing.
Leakage handling:
Minor leakage: Use inert materials to adsorb and avoid entering the sewer.
Large amount of leakage: dispose according to the specifications for hazardous chemicals, and use foam to cover to inhibit the vapor diffusion.
Fire extinguishing method:
Use water, carbon dioxide or foam to extinguish the fire and avoid direct impact on the leakage
