Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and antihistamines. It serves as a building block in organic reactions, especially in the preparation of heterocyclic compounds. Commonly employed in the development of dyes, fragrances, and agrochemicals due to its reactive aldehyde and hydroxymethyl functional groups. Also utilized in the preparation of ligands for catalysis and in the synthesis of polymers with specific thermal or mechanical properties.
