  • Applications

    2,7-Dimethyloctan-1-ol (CAS 15250-22-3) is a branched long-chain primary alcohol that is mainly used as a fragrance ingredient and cosmetic emollient; it can function as a solvent or processing aid in fragrance formulations, perfumes, and personal care products. It is commonly evaluated as a component in fragrance compositions and may serve as an intermediate for the synthesis of other aroma chemicals in industrial manufacturing. In coatings and inks, it can act as a processing aid or solvent for resins, and in household cleaning products it may contribute to odor profiles and formulation performance. Its use is typically governed by local regulations and formulation limits.
