Description

3-Hexenal is a high-purity, unsaturated aliphatic aldehyde with the distinctive green, grassy aroma characteristic of "leaf aldehyde." This compound is a key flavor and fragrance intermediate prized for its ability to impart fresh, natural green notes to complex formulations. It is essential for manufacturers in the flavor and fragrance industry, as well as for researchers in organic synthesis and chemical analysis. Our product, 3-Hexenal CAS NO 4440-65-7, is supplied with stringent quality control to ensure consistency and performance in sensitive applications.

Application

• Flavor & Fragrance Formulation: A primary building block for creating fresh, green, and cucumber-like top notes in perfumes, colognes, and fine fragrances.
• Food & Beverage Flavors: Used to replicate natural green flavors in products like vegetable juices, herbal infusions, and certain fruit flavors.
• Aroma Chemical Synthesis: Serves as a crucial intermediate in the synthesis of more complex aroma chemicals and specialty esters.
• Research & Development: Employed in academic and industrial R&D for studying aldol reactions, oxidation chemistry, and as a reference standard.
• Agrochemical Intermediates: Potential use in the synthesis of certain pheromones or bioactive molecules for crop protection.
• Cosmetic Ingredients: Incorporated into skincare and haircare products where natural, fresh olfactory profiles are desired.
