Description

trans-2-Hexenal is a high-purity, unsaturated aldehyde with the characteristic fresh, green, leafy aroma of cut grass. This compound is a key flavor and fragrance intermediate prized for its potent organoleptic properties and reactivity. It is essential for manufacturers in the flavor & fragrance, food, and specialty chemical industries seeking to create natural, green, or fruity sensory profiles. Our supply is characterized by consistent quality and reliable availability for global B2B partners.

Application

• Flavor & Fragrance Formulation: A primary building block for creating fresh, green, and fruity top notes in perfumes, cosmetics, and air fresheners.
• Food & Beverage Flavors: Used as a key component in flavor compositions for beverages, dairy products, and confectionery to impart natural "green" notes reminiscent of apple, strawberry, or unripe fruit.
• Agrochemical Semi-Synthesis: Serves as a chemical intermediate in the synthesis of certain pheromones and other bioactive compounds used in agricultural products.
• Organic Synthesis: A valuable reagent in fine chemical synthesis, particularly in aldol condensation and other reactions where its α,β-unsaturated carbonyl structure is utilized.
• Research & Development: Used in academic and industrial R&D labs as a standard or starting material for studying plant volatiles, insect attractants, and organic reaction mechanisms.
