  • Applications

    1-(4-Methyl-1,3-thiazol-2-yl)ethan-1-ol, CAS 7586-99-4, is primarily used as an organic synthesis intermediate: it serves as a building block for heteroaromatic compounds employed in pharmaceutical and agricultural research. It is also commonly used as a fragrance and flavor building block in perfumery and flavor chemistry, and may be employed in cosmetics/personal care as a scent ingredient or precursor. In industrial manufacturing, it supports the synthesis of specialty chemicals and related intermediates; its role is mainly as a synthetic building block rather than a solvent, and its use is subject to local regulations and formulation limits.
