Used as an intermediate in the synthesis of pharmaceuticals, particularly in the preparation of active ingredients for central nervous system (CNS) drugs. It plays a key role in the formation of ketones and carboxylic acid derivatives through nucleophilic substitution and coupling reactions. Commonly employed in research and development for building complex organic molecules due to its stability and reactivity profile. Also utilized in agrochemical synthesis for creating herbicidal and insecticidal compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for drug discovery and optimization.
