Description

trans-3-Hexen-1-ol is a naturally occurring, unsaturated six-carbon alcohol, also known as leaf alcohol, with the CAS number 544-12-7. This compound is prized for its powerful, fresh green odor reminiscent of cut grass and is a key building block in the synthesis of complex aroma molecules. It is an essential ingredient for flavor and fragrance chemists seeking to create authentic, natural-smelling green, fruity, and herbal profiles in fine perfumery, cosmetics, and food applications.

Application

• Fragrance Formulation: A primary component for imparting fresh, green, and leafy top notes in fine perfumes, colognes, and personal care products.
• Flavor Creation: Used to enhance or replicate natural green flavors in beverages, dairy products, confectionery, and savory food items.
• Aroma Chemical Intermediate: Serves as a crucial chiral synthon and starting material for the production of more complex esters and other aroma-active compounds.
• Cosmetic & Toiletry Products: Incorporated into soaps, shampoos, lotions, and detergents to provide a fresh, natural scent character.
• Household & Industrial Fragrances: Used in air fresheners, cleaning agents, and other functional products requiring a green, outdoor aroma.
• Research & Development: Employed in academic and industrial laboratories for olfactory research, sensory studies, and synthetic chemistry.
