Dimethyl pentadecanedioate is primarily utilized as a chemical intermediate in the synthesis of macrocyclic musk fragrances, such as cyclopentadecanolide (Exaltolide), which provide long-lasting, soft musky scents in perfumes, cosmetics, and scented products. Through cyclization reactions, it enables the production of these valuable fragrance bases known for stability and slow evaporation. It is not typically used directly as a fragrance ingredient but as a precursor. Additionally, due to its ester structure, it serves as an emollient or plasticizer in skincare formulations, offering smoothness, skin compatibility, and moisturizing effects without oily residue. It also finds applications in specialty polymers, lubricants, and other chemical syntheses requiring long-chain diesters.
