  • Applications

    In the flavor and fragrance industry, Nonanoic acid, (2E)-3,7-dimethyl-2,6-octadien-1-yl ester (CAS 68039-29-2)—the citronellyl ester of nonanoic acid—is used as a citrus–floral–fruity odorant, a scent modifier to boost diffusion and longevity in fine fragrances, soaps, and personal care; it also serves as a fragrance carrier/softener to smooth harsh notes in blends, an intermediate for synthesizing other aroma esters, and a household fragrance additive (detergents, air care), featuring medium volatility and broad solvency compatibility that enhance sensory profile and formulation stability.
