Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. It plays a role in modifying molecular structures to enhance drug efficacy and stability. Commonly employed in the preparation of amide derivatives through reactions with amines. Also utilized in the production of dyes and functionalized polymers due to its reactive chloroacetamido group. Its carboxylic acid functionality allows for further chemical modifications, making it valuable in organic synthesis and medicinal chemistry research.
