Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactive acid chloride group allows it to form amide and ester bonds, making it valuable in constructing complex organic molecules. Commonly employed in the preparation of herbicides and fungicides due to the presence of halogen substituents that enhance biological activity. Also utilized in the development of active ingredients in crop protection agents, where the bromo and chloro groups contribute to improved stability and target specificity. Its versatility in cross-coupling reactions further extends its use in medicinal chemistry for building halogenated aromatic frameworks.
