Description

3-Methylheptadecanoic Acid Methyl Ester is a high-purity branched-chain fatty acid ester, a key intermediate in advanced organic synthesis. Its defined structure and consistent quality make it essential for research and development requiring precise molecular building blocks. This compound is particularly valuable for pharmaceutical chemists, agrochemical researchers, and manufacturers of specialty lubricants and surfactants seeking to modify physical properties and enhance performance.

Application

• Pharmaceutical Intermediate: Serves as a crucial synthon in the development of novel active pharmaceutical ingredients (APIs), especially for lipid-based drug formulations.
• Agrochemical Synthesis: Used in the production of specialized pesticides and herbicides where its branched chain can influence bioavailability and environmental persistence.
• Specialty Lubricant & Grease Formulation: Acts as a synthetic base oil or additive to improve low-temperature fluidity, oxidative stability, and lubricity.
• Surfactant & Emulsifier Research: Provides a hydrophobic tail for creating novel non-ionic or anionic surfactants with tailored properties for detergents and personal care.
• Flavor & Fragrance Industry: Utilized as a precursor for synthesizing specific musk or fatty odorants in fine fragrance compositions.
• Polymer Plasticizer: Investigated as a potential bio-based or specialty plasticizer to modify the flexibility and processing of polymers.
• Analytical Reference Standard: Employed as a certified reference material (CRM) in gas chromatography (GC) and mass spectrometry (MS) for lipid analysis.
• Chemical Research: A valuable reagent in organic chemistry for studying esterification kinetics, lipid metabolism, and material science applications.
