Description

16-Methylheptadecanoic Acid Methyl Ester is a high-purity branched-chain fatty acid ester, valued for its role as a versatile chemical intermediate and reference standard in advanced synthesis. Its unique structure makes it a critical component for modifying the physical and chemical properties of polymers, lubricants, and specialty surfactants. This compound is essential for R&D laboratories and industrial manufacturers in the pharmaceutical, agrochemical, and performance materials sectors seeking to develop novel compounds with tailored characteristics.

Application

• Pharmaceutical Intermediate: Used in the synthesis of complex bioactive molecules and active pharmaceutical ingredients (APIs) where its branched chain introduces specific steric and lipophilic properties.
• Polymer & Resin Modifier: Acts as a plasticizer or comonomer to enhance flexibility, reduce crystallinity, and improve the low-temperature performance of specialized polymers.
• Lubricant & Fuel Additive Precursor: Serves as a key building block for synthesizing high-performance ester-based lubricants and fuel additives that offer superior stability and low volatility.
• Surfactant & Emulsifier Synthesis: Provides the hydrophobic backbone for creating non-ionic and anionic surfactants with specific branching for improved surface activity and biodegradability profiles.
• Agrochemical Formulations: Employed in the production of pesticide and herbicide intermediates to optimize penetration and environmental persistence.
• Analytical Reference Standard: Used in gas chromatography (GC) and mass spectrometry (MS) as a high-purity standard for method development and quality control in analytical laboratories.
• Fragrance & Flavor Chemistry: Functions as an intermediate for synthesizing musk-like odorants and other specialty aroma chemicals.
• Cosmetic Ingredient Intermediate: Utilized in the manufacture of emollients and texture-enhancing agents for personal care products.
