Description

Trans,trans-2,4-Decadien-1-Al is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct, fatty, and waxy odor profile. This compound matters as a key flavor and fragrance intermediate, prized for its ability to impart deep, natural fatty notes essential for authentic taste and scent creation. It is primarily needed by manufacturers in the flavor & fragrance, food processing, and cosmetic industries seeking to enhance product complexity and realism.

Application

• Flavor & Fragrance (F&F) Industry: A crucial building block for synthesizing and enhancing flavors with fatty, waxy, and deep-fried notes, such as in meat, nut, and fried food flavorings.
• Food Additive Production: Used in the creation of flavoring agents and additives to replicate authentic fatty tastes in processed foods, snacks, and savory products.
• Perfumery & Cosmetics: Serves as a fragrance component in soaps, detergents, and personal care products, contributing to complex, long-lasting scent profiles.
• Aroma Chemical Synthesis: Acts as a versatile intermediate in organic synthesis for producing more complex aroma chemicals and specialty aldehydes.
• Research & Development: Utilized in analytical and R&D laboratories as a reference standard and for studying the chemistry of unsaturated aldehydes.
