Syringaldehyde is primarily used in the field of organic synthesis as an intermediate for the production of pharmaceuticals, fragrances, and fine chemicals. Its aromatic structure and functional groups make it valuable in constructing complex molecules. It also serves as a building block in the development of bio-based polymers and resins, contributing to sustainable material science. In research, syringaldehyde is studied for its antioxidant properties and potential role in developing therapeutic agents. Additionally, it finds use in flavor and fragrance industries due to its pleasant, sweet, vanilla-like odor, often as a natural additive in food products or perfumes.
