Description

Docosane is a high-purity, straight-chain saturated hydrocarbon belonging to the alkane series, specifically a C22 n-alkane. This compound serves as a critical standard and intermediate in research and industrial applications due to its defined melting point and chemical stability. It is essential for manufacturers and R&D laboratories in the chemical, polymer, and specialty materials sectors seeking reliable, high-quality raw materials for synthesis, calibration, and formulation.

Application

• Chemical Synthesis Intermediate: Used in the production of surfactants, lubricant additives, and specialty chemicals.
• Reference Standard & Calibration: Acts as a primary standard in gas chromatography (GC) and other analytical techniques for instrument calibration and method validation.
• Polymer & Plasticizer Industry: Employed as a plasticizer, lubricant, or processing aid in polymer formulations and plastic manufacturing.
• Phase Change Materials (PCMs): Utilized in thermal energy storage systems due to its specific latent heat of fusion and melting point.
• Cosmetics & Personal Care: Functions as an emollient, thickener, or consistency regulator in creams, ointments, and lipsticks.
• Laboratory Research: Serves as a model compound in studies of crystallization, solid-state properties, and hydrocarbon chemistry.
