Used primarily as an intermediate in organic synthesis, it plays a key role in the production of pharmaceuticals, agrochemicals, and dyes. It is particularly valuable in the acylation reactions, where it introduces the 4-chlorobenzoyl group into various compounds. This chemical is also employed in the manufacture of herbicides and insecticides, contributing to crop protection. Additionally, it finds application in the synthesis of UV absorbers and stabilizers for polymers, enhancing the durability of materials exposed to sunlight. Its reactivity makes it a crucial component in the development of specialty chemicals and fine chemicals.
