Description

(Z,Z)-2,4-Decadienal is a high-purity, unsaturated aliphatic aldehyde known for its distinctive fatty, citrus-like aroma. This compound is a key flavor and fragrance intermediate, prized for its potent organoleptic properties and role in complex synthetic pathways. It is essential for manufacturers in the flavor & fragrance, food science, and fine chemical synthesis industries seeking to create authentic, high-impact sensory profiles or advanced chemical building blocks.

Application

• Flavor & Fragrance (F&F) Industry: A critical component for creating and enhancing flavors with fatty, citrus, and fried notes in processed foods, snacks, and beverages.
• Food Science & Aroma Chemistry: Used as a reference standard and as an additive in research to study and replicate the complex flavor profiles of cooked meats, fruits, and vegetables.
• Fine Chemical Synthesis: Serves as a versatile intermediate or building block in organic synthesis, particularly for producing more complex aldehydes, alcohols, and other derivatives.
• Cosmetics & Personal Care: Employed in trace amounts to formulate sophisticated fragrance accords for perfumes, lotions, and other scented products.
• Research & Development: Utilized in academic and industrial R&D labs for studying lipid oxidation, Maillard reaction products, and the chemistry of aroma generation.
