Application

Tert-butyl Chloroformate is primarily employed as a carboxyl-protecting agent in peptide synthesis, enabling the formation of tert-butoxycarbonyl (Boc) derivatives. It also serves as a key intermediate in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Its reactivity with amines and alcohols makes it invaluable for introducing the Boc group, which is later cleaved under mild acidic conditions.
