Description

(S)-Alpha,Alpha,4-Trimethylcyclohex-3-Ene-1-Methanethiol is a high-purity, chiral thiol compound characterized by its distinctive sulfurous and grapefruit-like aroma profile. This compound matters as a key chiral building block and fragrance ingredient, prized for its ability to impart unique, powerful, and long-lasting olfactory characteristics to sophisticated perfume formulations. It is primarily needed by flavor and fragrance houses, fine chemical manufacturers, and research institutions developing novel aroma chemicals or pharmaceutical intermediates.

Application

• Fragrance Industry: A key ingredient in the creation of high-end perfumes, colognes, and personal care products, contributing fresh, citrusy, and tropical nuances.
• Flavor Industry: Used as a flavoring agent to impart grapefruit, tropical fruit, or sulfury notes in food and beverage applications at very low concentrations.
• Fine Chemical Synthesis: Serves as a valuable chiral intermediate in the synthesis of more complex molecules for pharmaceuticals and agrochemicals.
• Aroma Chemical Research: Employed in R&D for studying structure-odor relationships and developing new proprietary fragrance molecules.
• Functional Perfumery: Used in household products, detergents, and air fresheners to provide a fresh, clean, and modern scent profile.
