n-Octane 98% / 99% CAS No. 111-65-9 Industrial & Laboratory Grade

Name: n-Octane 98% / 99% CAS No. 111-65-9 Industrial & Laboratory Grade
Brand: Richnow Chem

This high-purity n-Octane, available in 98% and 99% concentrations, is produced via advanced fractionation and hydrotreating technologies from petroleum refining streams. It features excellent solvency power, controlled evaporation rate, and exceptional chemical stability. As a key aliphatic hydrocarbon solvent with higher boiling point than lighter alkanes, it is widely used in specialty chemical synthesis, laboratory applications, and industrial formulations requiring longer open time. 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-Octane 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 125-126°C, providing extended evaporation time compared to lighter alkanes. Its higher molecular weight offers enhanced solvency for certain polymers and specialty chemicals. The narrow boiling range and high purity ensure consistent performance in critical synthesis and analytical applications. Available in multiple purity grades to suit different application requirements, from industrial formulations to high-purity laboratory work. Advanced GC analysis is employed to guarantee product purity and precise hydrocarbon composition, with strict control over aromatic content (<0.1%), sulfur compounds, and non-volatile residues. The product's chemical inertness makes it ideal for reactions requiring non-participating solvent media.

FAQ

What are the main advantages of n-Octane compared to lighter alkanes like n-Hexane or n-Heptane?

n-Octane offers a significantly higher boiling point (125-126°C vs. 69°C for n-Hexane), providing slower evaporation rates ideal for applications requiring extended open time. Its higher solvency power for certain polymers and reduced volatility make it safer for high-temperature reactions. The reduced vapor pressure also minimizes evaporative losses and worker exposure risks during extended processes.

How should n-Octane be handled in air-sensitive reactions?

For air-sensitive applications, n-Octane should be degassed through freeze-pump-thaw cycles or sparging with inert gas, and stored under nitrogen or argon. Our nitrogen-blanketed packaging option provides initial protection, but additional purification steps may be required for the most sensitive applications. Drying over molecular sieves is recommended for moisture-sensitive reactions.

What analytical specifications do you provide for n-Octane?

Each shipment includes a certificate of analysis with detailed specifications including purity by GC, distillation range, density at 20°C, refractive index, water content (Karl Fischer), non-volatile residues, and individual impurity profiles. Custom analytical packages including trace metal analysis or GC-MS characterization are available upon request.
