  • Applications

    (Z)-2-(3-Hexenyloxy)-3-methylpyrazine, CAS 94159-29-2, is primarily used as an aroma-active intermediate in fragrance chemistry, contributing green, aliphatic notes and serving as a building block for more complex perfume ingredients. It is commonly evaluated for use as a fragrance component in cosmetics and personal care products and may be employed in household products as a scent additive. In the flavor domain, it may be explored as a flavor/aroma ingredient, subject to regulatory approvals. In industrial manufacturing, it can function as an intermediate for the synthesis of specialty aroma compounds and can serve as a precursor in coatings or inks formulations that incorporate fragrance.
