Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure allows for selective interactions in asymmetric synthesis, making it valuable in creating enantiomerically pure drugs. Commonly employed in the preparation of central nervous system agents and anti-inflammatory compounds. Also utilized in agrochemicals for the production of herbicides and fungicides due to its stability and reactivity profile.
