  • Applications

    4-Methyltetracosane (CAS 76275-83-7) is a long-chain nonpolar hydrocarbon. In industry, it may be used as a nonpolar component in high-viscosity lubricants and base oils, and may participate in paraffin wax blends for waxes and coatings. In the field of polymers/plastics, it may be used as a paraffin additive to adjust viscosity and crystallization during plastic processing. In coatings and inks, it may serve as a wax additive to improve slip and surface properties of coatings. Additionally, it is often considered a reference standard or analytical substance in GC to evaluate the range of alkane chains and separation characteristics of oil/paraffin blends.
