Description

(E)-2-Octenal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct fatty, nutty aroma. This compound serves as a critical intermediate and flavor/fragrance ingredient, valued for its ability to impart authentic green, citrus, and waxy notes. It is essential for manufacturers in the flavor & fragrance, food processing, and fine chemical synthesis industries seeking reliable, high-quality raw materials for product development.

Application

• Flavor & Fragrance (F&F) Industry: A key aroma chemical used to create or enhance green, citrus, fatty, and nutty nuances in perfumes, cosmetics, and personal care products.
• Food Flavoring: Employed as a flavoring agent to replicate or boost the taste of citrus fruits, nuts, and certain vegetables in processed foods and beverages.
• Chemical Synthesis: Acts as a versatile building block in organic synthesis, particularly in the production of more complex aroma chemicals, pharmaceuticals, and agrochemical intermediates.
• Research & Development: Used as a reference standard or analytical reagent in R&D laboratories for sensory studies and chemical analysis.
