Description

trans-2-Heptenal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct fatty, green, and nutty aroma. This compound is a key flavor and fragrance intermediate, prized for its ability to impart authentic, natural character notes to complex formulations. It is essential for manufacturers in the flavor and fragrance, food, and cosmetic industries seeking to create or enhance profiles ranging from citrus and vegetable to roasted and fatty nuances.

Application

• Flavor & Fragrance Industry: A crucial building block for creating natural-tasting green, fatty, citrus, and nutty flavor profiles in beverages, dairy, confectionery, and savory products.
• Food Additives: Used as a flavoring agent to replicate or enhance the taste of various fruits, vegetables, nuts, and cooked foods.
• Perfumery: Serves as a fragrance ingredient in fine perfumes, cosmetics, and personal care products, adding fresh, green, and aldehydic top notes.
• Aroma Chemicals: Acts as a key intermediate in the synthesis of more complex aroma molecules and specialty chemicals.
• Research & Development: Utilized in analytical chemistry as a reference standard and in R&D for studying flavor chemistry and product development.
