  • Applications

    1-Phenyl-1-propanol (CAS 93-54-9) is an aromatic alcohol valued across fragrance, pharmaceutical and synthetic chemistry industries: in perfumery and cosmetics it serves as an intermediate for long-lasting floral notes and fixatives; in food and beverage manufacturing its ester derivatives impart delicate fruity and caramel nuances; in drug discovery it functions as a versatile scaffold for anti-inflammatory, antibacterial and neuroactive candidates, and owing to its stereochemical versatility it is a key chiral precursor for highly selective APIs; additionally, 1-phenyl-1-propanol can act as a mild reaction solvent, dispersion-control modifier in paints, stabilizing additive in polymers, and odor-masking agent in rubber processing, thereby enhancing mechanical performance and durability of finished materials.
