  • Applications

    3,4,5-Trimethoxybenzaldehyde (CAS 86-81-7) is an important precursor in the synthesis of aroma and flavor compounds, typically used as an intermediate to develop fragrance derivatives for the perfumery and flavor industries. It is also considered a precursor for cosmetic/personal care applications through fragrance formulations and base notes. In industrial manufacturing, this compound can serve as an intermediate in the synthesis of benzaldehyde derivatives and polymer/resin systems, coatings and inks. It may be used in household cleaning products to impart fragrance, and for the development of fragrance components in such products. Additionally, it is studied as an intermediate for pharmaceutical-related compounds and other complex organic syntheses, subject to regulatory and formulation limits.
