Description

(E)-5-Nonenal is a high-purity, unsaturated aliphatic aldehyde with a distinctive, powerful green, fatty, and melon-like odor. This compound is a key intermediate and fragrance ingredient valued for its ability to impart fresh, natural, and waxy-green olfactory nuances to complex formulations. It is essential for R&D chemists and product developers in the flavor and fragrance industry seeking to create or enhance sophisticated scent profiles. Our supply ensures consistent quality and reliable availability for global industrial applications.

Application

• Fragrance Compound: A crucial building block in the synthesis of high-value aroma chemicals and perfumery bases, contributing green, fatty, and melon notes.
• Flavor Ingredient: Used in trace amounts to create or enhance natural-tasting fruit (e.g., melon, cucumber) and fatty flavor profiles in food and beverage applications.
• Chemical Intermediate: Serves as a versatile precursor in organic synthesis for pharmaceuticals, agrochemicals, and specialty chemicals, leveraging its reactive aldehyde group and alkene functionality.
• Research & Development: Employed in academic and industrial laboratories for studying odorant-receptor interactions, green chemistry processes, and the development of new catalytic reactions.
• Consumer Product Fragrancing: Incorporated into fine perfumes, personal care products (soaps, lotions), and household products (detergents, air fresheners) to provide fresh, natural top notes.
