Description

2-Nonenal is a high-purity, unsaturated aliphatic aldehyde with a characteristic fatty, cucumber-like odor. This compound is a key flavor and fragrance intermediate valued for its potent organoleptic properties and versatility in fine chemical synthesis. It is essential for manufacturers in the flavor & fragrance, food & beverage, and cosmetic industries seeking to create or enhance specific sensory profiles.

Application

• Flavor & Fragrance Industry: A crucial component for imparting fatty, green, and cucumber-like notes in perfumes, colognes, and personal care products.
• Food & Beverage Flavoring: Used as a flavoring agent to replicate or enhance the taste of melon, cucumber, and other fresh, green notes in beverages, candies, and dairy products.
• Cosmetic & Personal Care: Incorporated into formulations for soaps, lotions, and shampoos to provide a fresh, natural scent profile.
• Chemical Synthesis: Serves as a valuable intermediate or building block in organic synthesis for pharmaceuticals and agrochemicals.
• Aroma Chemicals: A key raw material for creating complex aroma chemicals and essential oil reconstitutions.
• Research & Development: Used in analytical and R&D laboratories as a reference standard and for studying oxidation products in lipids.
