Chloroformates are relatively less dangerous route to prepare important families of compounds, the carbonates and carbamates. Carbonates are prepared by reaction with alcohol (or phenol) and carbamates are by reaction with an amine (primary or secondary).

Chloroformates are starting materials to prepare carbonate and carbamate derivatives that are used in the pharmaceutical and agrochemical industry.

Phenyl chloroformate is used as an intermediate for the synthesis of pharmaceuticals and agrochemicals especially for some carbamates (salt or ester of an amide of carbonic acid) which are used as insecticides, fungicides, herbicides, sprout inhibitors and biocides.
