Used primarily as an intermediate in organic synthesis, particularly in the pharmaceutical and agrochemical industries. It serves as a building block for the preparation of heterocyclic compounds due to the reactivity of the acid chloride group and the presence of the bromine atom, which allows for further functionalization through cross-coupling reactions. Commonly employed in the synthesis of ketones, amides, and esters via acylation reactions. Its bifunctional nature makes it valuable in constructing complex molecules where sequential derivatization is required. Also utilized in the development of active ingredients in crop protection agents and in the manufacture of specialty polymers.
