Used as an intermediate in organic synthesis, particularly in the preparation of carbamates and esters through alcohol protection and deprotection steps. It serves as a chloroethyl-protecting group for hydroxyl functionalities in complex molecule assembly, such as in pharmaceuticals and natural products. The compound enables selective reactions by temporarily blocking reactive alcohol sites, and the protecting group can be removed under mild basic or acidic conditions. Its reactivity makes it valuable in multi-step syntheses where controlled functional group manipulation is required.
