  • Applications

    Benzaldehyde, 2-ethenyl- (CAS 28272-96-0) is primarily used as a synthetic intermediate and fragrance-related raw material, serving as a precursor for aroma compounds and related odorants. It can also function as a flavor precursor or modifier in formulation workflows. In cosmetics and personal care, it is employed as an intermediate for fragrance ingredients and specialty additives. In the polymer and coatings sector, the vinyl aldehyde functionality enables use as a monomer or reactive intermediate for resins, plastics, coatings, and UV-curable systems. It also serves as a synthetic building block in pharmaceutical and specialty-chemical syntheses. Because of its aldehyde and vinyl groups, handling is subject to appropriate controls and local regulations.
