Used as a key intermediate in organic synthesis, particularly in the preparation of complex molecules for pharmaceuticals and agrochemicals. It serves as a building block for the introduction of both bromo and iodo substituents into aromatic compounds, enabling the creation of diverse chemical structures. Its reactivity as an acyl chloride makes it valuable in coupling reactions, such as amide bond formation, which are essential in drug development. Additionally, it is employed in the synthesis of materials for research in medicinal chemistry, where halogenated aromatic compounds are often explored for their biological activity.
