Used as an intermediate in the synthesis of pharmaceuticals and natural products, particularly in the preparation of vanillin derivatives and lignans. It serves in the development of bioactive molecules due to its aromatic aldehyde functionality and protected phenolic group, enabling selective reactions in multi-step organic syntheses. Commonly employed in the production of flavoring agents, fragrances, and antioxidants. Its structure allows for easy modification, making it valuable in medicinal chemistry for building more complex molecules with potential anti-inflammatory, antimicrobial, or anticancer activities.
