Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the production of anticoagulant and anti-inflammatory agents. It serves as a building block in organic synthesis due to the presence of multiple functional groups—aldehyde, hydroxyl, and chloro—that allow for selective reactions and derivatization. Commonly employed in the preparation of heterocyclic compounds and bioactive molecules, it plays a role in developing compounds with potential antimicrobial and antioxidant properties. Its structural features make it valuable in research settings for designing enzyme inhibitors and studying reaction mechanisms in medicinal chemistry.
