Description

cis-4-Heptenal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct, powerful, fatty, and green odor profile. This compound is a valuable organoleptic agent and a versatile synthetic intermediate in the production of complex flavor and fragrance molecules. It is essential for manufacturers in the flavor and fragrance industry seeking to create authentic, natural-tasting green, fatty, and vegetable-like nuances in their formulations.

Application

• Flavor & Fragrance Industry: A key aroma chemical used to impart fresh, green, fatty, and vegetable-like notes in perfumes, cosmetics, and food flavorings.
• Food & Beverage Flavors: Used in the creation of flavors for processed foods, snacks, and beverages where a natural green or unripe vegetable character is desired.
• Synthetic Intermediate: Serves as a crucial building block in organic synthesis for the production of more complex flavor and fragrance compounds, pharmaceuticals, and agrochemicals.
• Research & Development: Utilized in analytical chemistry as a reference standard and in R&D for studying the olfactory properties of aldehydes.
