Description

Ambrein CAS NO 473-03-0 is a high-purity, naturally occurring triterpenoid alcohol. This compound is valued for its unique chemical structure and serves as a key intermediate in the synthesis of valuable fragrance and pharmaceutical ingredients. It is primarily sought after by manufacturers in the fragrance, flavor, and fine chemical industries for its role in creating complex, high-value molecules.

Application

• Fragrance & Flavor Industry: A crucial intermediate in the synthesis of Ambrox® and other ambergris-type odorants, imparting warm, woody, and amber notes to premium perfumes and colognes.
• Fine Chemical Synthesis: Serves as a versatile chiral building block for the production of specialized steroids and other bioactive triterpenoids.
• Pharmaceutical Research: Used as a reference standard and starting material in pharmacological studies exploring anti-inflammatory or neuroactive properties.
• Aroma Chemical Production: Employed in the manufacture of high-value aroma chemicals that replicate natural ambergris, a rare animal-derived fragrance material.
