Description

8-Methylnonanal is a high-purity aliphatic aldehyde with a distinctive, powerful odor profile. This compound is valued for its role as a key fragrance and flavor intermediate, contributing green, waxy, and citrus-like nuances to complex formulations. It is primarily sought after by manufacturers in the fragrance, flavor, and fine chemical synthesis industries for creating sophisticated aromatic products.

Application

• Fragrance Industry: A crucial building block for creating and modifying perfume accords, imparting fresh, green, and waxy notes in fine fragrances, cosmetics, and personal care products.
• Flavor Industry: Used as a flavoring agent to enhance or create citrus, melon, and green flavor profiles in food and beverage applications.
• Chemical Synthesis: Serves as a versatile intermediate in organic synthesis, particularly in the production of more complex fragrance molecules, alcohols (via reduction), and acids (via oxidation).
• Aroma Chemicals: A key raw material for the manufacture of other high-value aroma chemicals and specialty odorants.
• Research & Development: Utilized in R&D laboratories for studying olfaction, developing new synthetic routes, and creating novel specialty chemicals.

Quality Control

Our 8-Methylnonanal is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, IR, and NMR to verify identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, strong bases, and strong reducing agents. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in opened containers. Recommended storage temperature: 2-8°C.
