Used as a key intermediate in the synthesis of fluorinated pharmaceuticals, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its nitrile group allows for versatile functionalization, enabling conversion to amines, carboxylic acids, or tetrazoles, which are common pharmacophores. The presence of fluorine enhances metabolic stability and membrane permeability in final drug compounds. Commonly employed in research and development for novel bioactive molecules and in process chemistry for scalable drug manufacturing.
