Description

trans-2-Decenal is a high-purity, unsaturated aliphatic aldehyde characterized by its distinct fatty, citrus-like odor. This compound is a valuable intermediate and flavor/fragrance ingredient prized for its ability to impart green, waxy, and orange-like notes. It is essential for manufacturers in the flavor and fragrance, food processing, and fine chemical synthesis industries seeking to create complex organoleptic profiles or specific chemical building blocks.

Application

• Flavor & Fragrance (F&F) Industry: A key component in creating and enhancing flavors for citrus, orange, mandarin, and fatty nuances in food products, beverages, and confectionery. Also used in perfumery for fresh, green, and waxy accords.
• Food Processing: Used as a flavoring agent to replicate or boost natural citrus flavors in processed foods, dairy products, and soft drinks.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis, particularly in the production of more complex aroma chemicals, pharmaceuticals, and agrochemicals.
• Research & Development: Utilized in analytical laboratories as a reference standard and in R&D for studying flavor chemistry, oxidation reactions, and sensory science.
