Used primarily as a reactive intermediate in organic synthesis, this chemical is employed to introduce functional groups or modify molecules in pharmaceuticals and polymers. It is particularly useful in the preparation of prodrugs, where it helps in attaching protective groups that can be cleaved under specific conditions to release the active drug. In polymer chemistry, it serves as a cross-linking agent, enhancing the mechanical properties and stability of materials. Its application extends to surface modification, where it is used to alter the properties of materials for improved adhesion or biocompatibility.
