n-Undecane 98% / 99% CAS No. 1120-21-4 Industrial & Laboratory Grade

Name: n-Undecane 98% / 99% CAS No. 1120-21-4 Industrial & Laboratory Grade
Brand: Richnow Chem

This high-purity n-Undecane, available in 98% and 99% concentrations, is produced via advanced fractionation and hydrotreating technologies from petroleum refining streams. It features excellent solvency power, very low volatility, and exceptional chemical stability. As a higher molecular weight aliphatic hydrocarbon solvent, it is widely used in specialty chemical synthesis, industrial formulations, and research applications requiring a non-polar medium with minimal evaporation loss at elevated temperatures. Its high purity and consistent performance make it ideal for critical applications requiring precise solvent properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial and laboratory standards.

Product Features

n-Undecane is manufactured using advanced fractionation and purification technologies, ensuring consistent quality and precise boiling characteristics. The product features excellent solvency for non-polar compounds with a boiling point of 196°C, providing exceptional stability during high-temperature processing with virtually no evaporative loss below 150°C. Its molecular weight of 156.31 g/mol offers enhanced solvency for high molecular weight polymers, waxes, and specialty chemicals. The extremely low vapor pressure (0.3 mmHg at 25°C) dramatically reduces worker exposure risk and evaporative emissions compared to lighter hydrocarbons. The narrow boiling range and high purity ensure consistent performance in critical synthesis and analytical applications.

FAQ

What are the main advantages of n-Undecane compared to medium-chain alkanes like n-Decane or n-Nonane?

n-Undecane offers an even higher boiling point (196°C vs. 174°C for n-Decane) and significantly lower vapor pressure (0.3 mmHg vs. 1.3 mmHg for n-Decane), providing exceptional stability at elevated temperatures with virtually no evaporative loss during extended reactions. Its higher solvency power for very high molecular weight compounds and enhanced thermal stability make it ideal for demanding high-temperature industrial processes. The extremely low volatility also virtually eliminates worker exposure concerns and solvent losses during prolonged processing.

What purity grades are available for n-Undecane and their typical applications?

The 98% grade is suitable for most industrial applications including high-temperature solvent formulations and general synthesis. The 99% grade provides higher purity for sensitive applications such as pharmaceutical intermediate synthesis, analytical reference standards, and specialty chemical production where precise composition and minimal impurities are critical. Research-grade material (99.5%+) is available for advanced applications requiring exceptional purity, including physical property standards, spectroscopic studies, and certified reference materials.
