Used in the synthesis of flavor and fragrance compounds due to its aromatic aldehyde structure with phenolic characteristics. Its hydroxy and methyl substituents contribute to stability and sensory properties, making it valuable in creating artificial flavors, particularly for fruity or vanilla-like notes. Also serves as an intermediate in organic synthesis for pharmaceuticals and agrochemicals where substituted benzaldehydes are required. Its reactivity allows for derivatization through oxidation, reduction, or condensation reactions in fine chemical manufacturing.
