Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anticoagulant drugs and certain anti-inflammatory agents. It serves as a building block in organic reactions where the aldehyde and hydroxyl groups allow for functionalization into more complex molecules. Commonly employed in the development of fine chemicals and agrochemicals due to its reactive sites and stability under various reaction conditions. Also utilized in the preparation of dyes and fragrances where substituted benzaldehyde derivatives are required.
