  • Applications

    2-Benzylbutanal (CAS 24569-60-6) is primarily used as a synthetic intermediate in fragrance and flavor chemistry, functioning as an odorant and as a fragrance-building block in perfumery. It may be employed as a flavor intermediate in related product development, and, in cosmetics and personal care, as a fragrance ingredient. In industrial manufacturing it serves as a precursor in organic syntheses and related downstream chemicals; it can also be incorporated into household products as a fragrance component in cleaners, detergents, and air-freshener formulations. Usage is subject to local regulations and formulation limits.
