Description

n-Hexadecane is a high-purity, straight-chain alkane hydrocarbon, also known as cetane, with the CAS number 544-76-3. It serves as a critical reference standard and performance benchmark across multiple high-tech industries due to its defined chemical structure and consistent properties. This compound is essential for manufacturers and research laboratories in the petrochemical, lubricant, pharmaceutical, and specialty chemical sectors who require a reliable and pure hydrocarbon solvent or calibrant.

Application

• Cetane Reference Fuel: Primary standard for determining the cetane number of diesel fuels, critical for engine performance testing and fuel quality control.
• Chemical Synthesis & Intermediate: Used as a starting material or solvent in organic synthesis and the production of surfactants, lubricant additives, and other specialty chemicals.
• Calibration Standard: Essential reference material for gas chromatography (GC), high-performance liquid chromatography (HPLC), and other analytical instrumentation.
• Lubricant & Grease Formulation: Acts as a base oil or additive component in specialty lubricants and greases requiring high stability.
• Pharmaceutical & Cosmetic Excipient: Employed as an emollient, solvent, or viscosity modifier in topical formulations and cosmetic products.
• Research & Development: Used in academic and industrial R&D for studies on hydrocarbon behavior, phase transitions, and as a model compound in physical chemistry.
• Plasticizer & Processing Aid: Functions as a processing aid or secondary plasticizer in polymer and rubber manufacturing.
• Heat Transfer Fluid: Suitable for use in non-pressurized heat transfer systems due to its thermal stability.
