Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of certain antibiotics and antifungal agents. It serves as a building block in organic synthesis due to the presence of both aldehyde and hydroxyl functional groups, which allow for diverse chemical modifications. Commonly employed in the development of fine chemicals and bioactive molecules, especially those requiring substituted benzaldehyde derivatives. Its reactivity makes it suitable for use in condensation reactions, such as the synthesis of heterocyclic compounds. Also utilized in research settings for the preparation of natural product analogs and enzyme inhibitors.
