Description

2-Methylundecanal is a high-value, long-chain aliphatic aldehyde prized for its unique waxy, citrus-like, and slightly floral odor profile. This compound matters as a versatile fragrance ingredient and key intermediate, offering perfumers and flavorists a sophisticated tool for creating complex, long-lasting olfactory effects. It is primarily needed by manufacturers in the fragrance, flavor, and fine chemical synthesis industries for applications ranging from premium perfumery to specialty chemical production. The product is supplied under stringent quality control to ensure consistency for demanding commercial applications.

Application

• Fragrance Industry: A key component in the formulation of fine perfumes, colognes, and personal care products, imparting fresh, citrus, waxy, and aldehydic notes.
• Flavor Industry: Used as a flavoring agent to create or enhance citrus, waxy, and fruity nuances in food and beverage products.
• Functional Perfumery: Incorporated into soaps, detergents, fabric softeners, and household cleaners to provide a fresh, clean, and lasting scent.
• Chemical Synthesis: Serves as a valuable intermediate in organic synthesis for the production of more complex fragrance molecules, pharmaceuticals, and agrochemicals.
• Aromatherapy & Candles: Used in specialty essential oil blends and scented candles for its distinctive and diffusive aromatic character.

Quality Control

Our 2-Methylundecanal is produced and tested to meet the high standards required by the fragrance and flavor industries. Each batch undergoes rigorous analytical testing, including gas chromatography (GC), to ensure identity, purity, and olfactory consistency. A comprehensive Certificate of Analysis (COA) detailing assay, physical properties, and organoleptic assessment is available for every shipment. Our quality management system ensures traceability and compliance with relevant industry guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flames. Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality and shelf life.
