Description

Trans,trans-2,4-Nonadienal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinctive fatty, waxy, and cucumber-like aroma. This compound is a key flavor and fragrance intermediate valued for its potent organoleptic properties and versatility in formulation. It is essential for manufacturers in the flavor, fragrance, and food industries seeking to create or enhance specific sensory profiles in their products.

Application

• Flavor & Fragrance (F&F) Industry: A primary building block for creating and modifying flavors and aromas, imparting fatty, green, and cucumber notes.
• Food & Beverage Flavors: Used as a flavoring agent in products requiring a fresh, green, or melon-like character, such as beverages, candies, and dairy products.
• Perfumery & Cosmetics: Incorporated into fragrance compositions for soaps, detergents, lotions, and fine perfumes to add natural, vegetative top notes.
• Aroma Chemical Synthesis: Serves as a crucial intermediate in the synthesis of more complex aroma chemicals and specialty ingredients.
• Research & Development: Utilized in analytical chemistry as a reference standard and in R&D for studying flavor chemistry and sensory science.
