Used in the synthesis of fragrance compounds due to its aromatic aldehyde structure and ether linkage, contributing to sweet, floral, and slightly fruity notes in perfumery. Its hydroxyethoxy group enhances solubility in polar solvents, making it suitable for aqueous-based cosmetic and personal care formulations. Also serves as an intermediate in organic synthesis for pharmaceuticals and agrochemicals, where the aldehyde functionality allows for easy derivatization into imines, alcohols, or carboxylic acids. Stable under normal storage conditions, it is favored in industrial applications requiring long shelf life and consistent reactivity.
