2-Cyanophenylacetic Acid is primarily used in the synthesis of various pharmaceutical compounds. It serves as a key intermediate in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) and other therapeutic agents. The compound is also utilized in organic synthesis to create complex molecules, particularly in the development of active pharmaceutical ingredients (APIs). Additionally, it finds application in the preparation of fine chemicals and specialty chemicals used in research and industrial processes. Its role in the synthesis of heterocyclic compounds makes it valuable in medicinal chemistry for designing new drugs with potential biological activities.
