Description

3,20,20-Trimethylhenicosanoic Acid Methyl Ester is a high-purity, branched-chain fatty acid methyl ester (FAME) with the CAS number 55334-79-7. This specialty ester is valued for its unique molecular structure, which imparts specific physical and chemical properties useful in advanced material synthesis and research. It serves as a critical intermediate or standard for industries focused on fine chemicals, lubricant additives, and polymer research.

Application

• Chemical Intermediate: Acts as a key building block in the synthesis of more complex branched-chain surfactants and specialty polymers.
• Lubricant & Fuel Additive Research: Used in R&D to study the effects of highly branched structures on viscosity, pour point, and oxidative stability in formulations.
• Analytical Standard: Serves as a high-purity reference standard in gas chromatography (GC) and mass spectrometry (MS) for the identification and quantification of similar fatty acid esters.
• Pharmaceutical & Cosmetic Research: Investigated for its potential as a novel emollient or penetration enhancer due to its specific lipid-like properties.
• Material Science: Explored as a monomer or plasticizer in the development of specialized polymeric materials with tailored flexibility and hydrophobicity.

Quality Control

Our production of 3,20,20-Trimethylhenicosanoic Acid Methyl Ester adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including GC, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to preserve stability.
