  • Applications

    2,2,5,9-Tetramethyldeca-4,8-dienal (CAS 53131-20-7) is primarily employed as a synthetic odorant in perfumery, contributing a branched, distinctive note to fragrance formulations and, at low concentrations, to some flavor systems. It may be used as a fragrance ingredient in cosmetics and personal care products, and as a scent additive in household cleaners and air fresheners when permitted by local regulations. In industrial manufacturing, it can serve as a precursor or building block in the synthesis of other aroma chemicals, enabling customization of scent profiles in various matrices. Additionally, it is sometimes considered as a fragrance additive for coatings, inks, or polymers to impart or modulate aroma in packaged goods, under appropriate regulatory controls.
