Description

(-)-α-Terpineol CAS NO 10482-56-1 is a high-purity, optically active monoterpene alcohol valued for its distinctive lilac-like aroma and versatile chemical functionality. This specific enantiomer is particularly significant in the synthesis of fine chemicals and as a chiral building block, offering superior olfactory characteristics compared to its racemic or opposite enantiomer forms. It is an essential ingredient for manufacturers in the fragrance, flavor, and pharmaceutical intermediates sectors seeking consistent quality and specific stereochemistry.

Application

• Fragrance & Perfumery: A key chiral component in high-end perfumes, soaps, detergents, and cosmetic formulations for its fresh, floral lilac scent.
• Flavoring Agent: Used in food and beverage flavorings to impart subtle floral and citrus notes, where the specific enantiomer can influence the flavor profile.
• Pharmaceutical Intermediates: Serves as a chiral precursor or synthon in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Industrial Aromatics: Employed in air fresheners, household cleaners, and industrial deodorants for its effective and pleasant masking properties.
• Chemical Synthesis: Utilized as a starting material or intermediate in organic synthesis for producing derivatives used in agrochemicals and other specialty chemicals.
• Solvent & Dispersant: Acts as a solvent for resins and a dispersing agent in various industrial processes.
