Description

n-Eicosane is a high-purity, long-chain linear alkane (C20H42) valued for its defined chemical structure and consistent physical properties. It serves as a critical standard and reference material in analytical chemistry and as a versatile building block in advanced material synthesis. This product is essential for industries requiring precise calibration, controlled phase-change behavior, or hydrophobic hydrocarbon chains, including petrochemical analysis, specialty wax manufacturing, and advanced polymer research.

Application

• Gas Chromatography (GC) Standard: Used as a primary reference compound for calibrating retention times and quantifying hydrocarbons due to its well-defined boiling point and purity.
• Phase Change Material (PCM): Incorporated into thermal energy storage systems for its stable melting and freezing characteristics.
• Specialty Wax & Lubricant Formulation: Acts as a high-melting-point component to modify the hardness, gloss, and texture of synthetic waxes and specialty lubricants.
• Organic Synthesis Intermediate: Serves as a starting material or chain extender in the synthesis of surfactants, polymers, and other long-chain derivatives.
• Reference Material in Research: Employed in academic and industrial laboratories for studying alkane properties, crystallization behavior, and surface science.
• Hydrophobic Agent: Used to impart water-repellent characteristics to coatings, textiles, and composite materials.
