Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for modifying molecular structures to enhance drug stability and bioavailability. Its functional groups allow for selective chemical transformations, making it valuable in medicinal chemistry research and development. Commonly employed in esterification and amidation reactions to create active pharmaceutical ingredients (APIs) with improved pharmacokinetic profiles.
