  • Applications

    2,4,6,10-Tetramethylpentadecane (CAS 20265-60-5) is a branched C19 alkane that is typically used as a non-polar solvent and diluent in industrial formulations, serving as a high-boiling carrier for coatings, inks, and adhesives. It also functions as a lubricant base stock or viscosity modifier in specialty lubricants and metalworking fluids. In cosmetics and personal care, it can be used as a solvent or carrier for fragrance and active ingredients, providing a lightweight, low-odor medium. In analytical chemistry, it is employed as a reference material or calibration standard for hydrocarbon separation methods (e.g., GC) due to its well-defined structure. Additionally, it may be used as a processing aid or diluent in polymer and plastics formulations where a non-polar, hydrophobic medium is required.
