Cyclopentane

Cyclopentane (CAS 287-92-3) is a cyclic hydrocarbon solvent supplied under trade names including Zeonsolv HP, Marukazol FH, and Exxsol HP 95. It carries no assigned E-code and is catalogued under HS code 29021990. It is also referenced in technical literature as NSC 60213.

In rigid polyurethane foam manufacturing, cyclopentane functions as a physical blowing agent, expanding the foam matrix as it volatilises during the exothermic reaction. In pharmaceutical and flavour applications, it acts as a carrier solvent, dissolving active compounds and enabling controlled dispersion. Its low polarity makes it selective for non-polar extraction and formulation processes.

Cyclopentane is available as a high-purity colourless liquid suitable for REACH-compliant supply within the European market. Grades meeting FCC specifications are accessible for flavour-related applications. Packaging formats typically include drums and isotanks, with documentation available to support procurement and regulatory submissions.
