  • Applications

    Citronelloxyacetaldehyde (CAS 7492-67-3) is primarily used as an intermediate in fragrance chemistry, enabling the synthesis of citronellol- and citrus-derived aroma compounds. It can be employed as a fragrance ingredient or odorant in perfumery and in cosmetics/personal care formulations, contributing citrus/green notes. In household products, it may be added as a fragrance component to impart a fresh citrus scent. As a reactive aldehyde derivative, it is sometimes evaluated for use in the production of related fragrance chemicals and as a building block in coatings/inks with fragrance attributes. It is typically handled as an intermediate and is subject to local regulations and formulation limits.
