Description
n-Pentane 99% (CAS No. 109-66-0) is a high-purity grade of this straight-chain aliphatic hydrocarbon. Specifically, we produce it for applications where consistency and low contaminant levels matter — including laboratory use, chromatography, and precision extraction processes.
Compared to the 95% grade, this purity level suits customers who need tighter control over trace impurities. However, for large-scale foam blowing and general industrial use, our n-Pentane 95% is usually the more cost-effective choice.
Because this grade carries a lower isopentane content and tighter sulfur limits than the standard commercial grade, it performs reliably in settings where trace contaminants could skew results or reduce process consistency. Many laboratories and specialty manufacturers treat it as their default choice when standard-grade material isn’t tight enough.

Applications for n-Pentane 99%
What’s more, laboratories use this grade for analytical work, chromatography, and precision extraction. Because of its low contaminant levels, it also suits specialty solvent applications where trace impurities could interfere with results. As a result, this grade is often the default choice for research and quality-control settings. In addition, some specialty foam and coating formulations call for this tighter specification when consistency between batches is critical.
