Chloromethyl chloroformate is a colorless liquid, which was earlier employed in its gaseous form as warfare chemical under the name Palite gas. In chemicals industry, for its extreme reactivity, it is used to make pharmaceuticals and intermediates.
The chloroformic acid ester is produced by allylic chlorination of methyl chloroformate, which in turn is formed by reaction of methanol with phosgene.
Applications in Pharmaceuticals
The ester is a KRM for the manufacture of APIs:
|Ronidazole, an antibiotic|
|Tenofovir, an anti-HIV drug|
|Aminocarbonyloxymethyl ester of Diclofenac and Flufenamic Acid|
|Monomethoxypoly(ethylene glycol) prodrug of Cyclosporine A|
Applications in Intermediates
Chloromethyl chloroformate forms a variety of intermediates such as:
|Chloromethyl ethyl carbonate|
|Chloromethyl isopropyl carbonate|
|Appearance||–||Clear colorless to yellow liquid|
|Solubility||–||Should be soluble in dichloromethane|
