Description

5,9-Dimethyl-2-Decenal is a high-value, unsaturated aliphatic aldehyde characterized by its unique, powerful, and diffusive green, citrusy, and waxy odor profile. This compound matters as a key fragrance ingredient and flavoring agent, prized for its ability to impart fresh, natural nuances to complex formulations. It is primarily needed by manufacturers in the flavor and fragrance industry, as well as by research and development chemists exploring novel aroma chemicals and synthetic pathways.

Application

• Fragrance Formulation: A key component in creating fresh, green, and citrusy top notes for fine perfumes, personal care products (soaps, shampoos), and household cleaners.
• Flavor Enhancement: Used to impart or enhance citrus, waxy, and green flavor characteristics in food and beverage applications, often at low concentrations.
• Aroma Chemical Synthesis: Serves as a valuable intermediate or starting material in the synthesis of more complex fragrance molecules and specialty chemicals.
• Research & Development: Utilized in academic and industrial R&D for studying structure-odor relationships, reaction mechanisms, and developing new catalytic processes.
• Functional Fluids & Additives: Potential use as an intermediate in the production of lubricants, plasticizers, or other specialty organic compounds.

Quality Control

Our 5,9-Dimethyl-2-Decenal is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high purity, consistent odor profile, and conformity to internal specifications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, an inert atmosphere (nitrogen or argon) is recommended to maintain stability and purity. Keep away from strong oxidizing agents.
