The Ethyl chloroformate, with the CAS registry number 541-41-3,is also known as Ethyl chlorocarbonate; Carbonchloridic acid ethyl ester. It belongs to the product categories of Pharmaceutical Intermediates;Organics. This chemical's molecular formula is C₃H₅ClO₂ and molecular weight is 108.52.Its EINECS number is 208-778-5. What's more,Its systematic name is Ethyl chloroformate. It is a Colorless to yellow liquid which can be used as organic synthesis intermediate for the Preparation of isocyanate, pharmaceuticals, pesticides, herbicides and flotation agent. Also used as a solvent. And it decomposes slowly in water to form ethanol, HCl, and CO2. Attacks many metals especially in humid atmosphere. It may react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts.
