Description

Dimethyloctadienal, specifically (E)-3,7-Dimethyl-3,6-octadienal, is a high-value, unsaturated aliphatic aldehyde characterized by its fresh, citrus-like aroma. This compound matters as a versatile and potent fragrance intermediate, prized for its ability to impart natural, green, and floral nuances to complex scent profiles. It is primarily needed by manufacturers in the flavors and fragrances, cosmetics, and personal care industries seeking to create sophisticated, high-performance aroma chemicals.

Application

• Fragrance & Perfumery: A key building block for creating fresh, citrusy, and floral top notes in fine perfumes, colognes, and eau de toilettes.
• Functional & Household Products: Used in the scent formulation of soaps, detergents, fabric softeners, and air fresheners to provide a clean, natural character.
• Cosmetics & Personal Care: Incorporated into lotions, shampoos, and body washes as a fragrance component to enhance product appeal.
• Flavor Enhancement: Employed in trace amounts to add complexity and natural citrus notes to certain flavor compositions.
• Chemical Synthesis: Serves as a valuable chiral intermediate or starting material in the synthesis of more complex aroma molecules and fine chemicals.
