Used primarily in organic synthesis as a reagent for introducing the trichloroethoxycarbonyl (Troc) protecting group for amines and alcohols. This protecting group is stable under various reaction conditions but can be selectively removed using zinc in acetic acid or other reducing agents. It is also employed in peptide synthesis to protect amino groups, ensuring specific reactions occur at desired sites without interference. Additionally, it finds application in the preparation of pharmaceuticals and agrochemicals, where selective protection and deprotection of functional groups are crucial. Its reactivity with nucleophiles makes it useful in creating complex molecular structures.
