  • Applications

    4-Ethylbenzyl alcohol (CAS 768-59-2) is primarily used as a building block in fragrance and cosmetics applications, serving as a precursor to aroma compounds and related esters and aldehydes for perfumes and personal care products. In fragrance chemistry, it can be oxidized or transformed to generate aroma-related derivatives used as components in scent formulations, and it functions as a starting material for various aroma-building syntheses in industrial manufacturing. It may also find use as an intermediate in flavor/aroma chemistry, subject to formulation limits and local regulations.
