Description

Trans,trans-2,4-Nonadienal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct, powerful odor. This compound is a key flavor and fragrance ingredient, prized for its ability to impart fatty, waxy, and cucumber-like notes to complex formulations. It is essential for manufacturers in the flavor and fragrance, food, and cosmetic industries seeking to create authentic and sophisticated sensory profiles. Our supply ensures consistent quality and reliable availability for your production needs.

Application

• Flavor & Fragrance Industry: A crucial component in creating and enhancing flavors for processed foods, snacks, and beverages, particularly to impart fatty, fried, or cucumber notes.
• Perfumery: Used as a top or middle note in fine fragrances, soaps, and detergents to add fresh, green, and waxy olfactory characteristics.
• Food Additive: Employed as a flavoring agent (FEMA/GRAS status typically applicable) in margarines, cooking oils, and various savory products to replicate natural taste profiles.
• Cosmetic Formulations: Incorporated into lotions, creams, and personal care products to provide a specific scent or to mask base odors.
• Chemical Synthesis: Serves as a valuable intermediate or starting material in organic synthesis for producing more complex flavor molecules or specialty chemicals.
• Research & Development: Used in analytical laboratories as a reference standard for quality control and in sensory science studies.
