Description

4-Heptenal is a seven-carbon unsaturated aldehyde with the CAS NO 62238-34-0, valued for its distinctive green, fatty, and slightly fishy aroma profile. This compound serves as a versatile and potent flavor and fragrance intermediate, enabling the creation of complex natural notes in various formulations. It is primarily sought after by manufacturers in the flavor, fragrance, and fine chemical synthesis industries for its organoleptic properties and utility as a building block.

Application

• Flavor & Fragrance Industry: A key component in creating and enhancing green, fatty, and marine notes for perfumes, cosmetics, and personal care products.
• Food Flavorings: Used to impart or reinforce natural, fatty, and creamy nuances in processed food flavors, particularly those mimicking dairy, nuts, or certain fruits.
• Chemical Synthesis: Acts as a valuable intermediate or starting material in organic synthesis for pharmaceuticals, agrochemicals, and other specialty chemicals.
• Aroma Chemical Production: Employed in the manufacture of more complex aroma chemicals through reactions like aldol condensation or hydrogenation.
• Research & Development: Utilized in analytical and R&D laboratories as a reference standard and for studying the chemistry of unsaturated aldehydes.
