Description

1-Methoxyundecane is a high-purity, linear alkyl methyl ether, also known as methyl undecyl ether. This compound serves as a versatile intermediate and solvent, valued for its specific hydrophobic and surfactant properties. It is primarily utilized in the synthesis of specialty chemicals, fragrances, and performance materials across the pharmaceutical, agrochemical, and flavor & fragrance industries.

Application

• Fragrance and Flavor Intermediate: Acts as a key building block for synthesizing specific musk-like or green odorant molecules.
• Pharmaceutical Synthesis: Used as a protected intermediate or a lipophilic moiety in the development of active pharmaceutical ingredients (APIs).
• Agrochemical Formulations: Employed as a solvent or co-solvent in pesticide and herbicide concentrates.
• Specialty Surfactants: Serves as a hydrophobic precursor for non-ionic surfactants and emulsifiers.
• Organic Synthesis: Functions as an alkylating agent or a protecting group reagent in various organic transformations.
• Lubricant Additive: Used as a component in the formulation of synthetic lubricants and functional fluids.
• Polymer Modification: Can be incorporated into polymers to modify surface properties and flexibility.
• Research & Development: A valuable standard and reagent in chemical research for method development and material science.

Quality Control

Our 1-Methoxyundecane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation, to ensure it meets stringent specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. 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. Recommended storage temperature: 2-8°C to minimize volatility and degradation.
