Description

2,4-Dodecadienal 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 ability to impart complex, natural character notes to formulations. It is essential for manufacturers in the flavor, fragrance, and food ingredient industries seeking to create authentic and sophisticated sensory profiles.

Application

• Flavor & Fragrance (F&F) Industry: A critical building block for synthesizing complex aroma chemicals and natural flavor compounds.
• Food Flavoring: Used to create and enhance citrus, fatty, and waxy flavor notes in processed foods, beverages, and confectionery.
• Perfumery: Serves as a valuable component in fragrance compositions, adding depth and natural character to fine perfumes and cosmetic products.
• Aroma Chemical Synthesis: An important intermediate in the production of other aldehydes and related aroma-active molecules.
• Research & Development: Used in analytical chemistry as a reference standard and in R&D for studying flavor chemistry and sensory science.
