Cyclopentane CAS 287-92-3

Cyclopentane (CAS 287-92-3) is a volatile cycloalkane, a colorless, clear liquid with a very low flash point. Most goes into rigid polyurethane and polyisocyanurate foam as a blowing agent for refrigerator cabinets, insulation panels and spray foam, replacing ozone depleting agents. It also works as a nonpolar solvent, extraction medium and synthesis feedstock. UATChem supplies foam blowing and industrial grades in 50 kg plastic drums and steel drums, with COA, TDS, SDS and samples on request.

What Cyclopentane Is

Cyclopentane is a saturated five membered ring hydrocarbon and the most volatile common cycloalkane. The colorless liquid is nonpolar, nearly insoluble in water and miscible with alcohol, ether and acetone, and evaporates fast. A flash point below room temperature means high flammability, so cool storage away from ignition sources is required. UATChem supplies foam blowing and industrial material, with assay and impurities on the COA and TDS.

Foam Blowing, Solvent and Synthesis Uses

  • Foam blowing. It is a physical blowing agent for rigid polyurethane and polyisocyanurate foam used in refrigerator and freezer cabinets, insulation boards, pipe sections and spray foam, with no ozone depleting potential. It is sometimes blended with normal or iso pentane to tune foam behavior.
  • Solvent and extraction. It serves as a nonpolar hydrocarbon solvent, an extraction and cleaning medium and a chromatography reference where a defined volatile cut is wanted.
  • Synthesis. It works as a feedstock and process material in organic synthesis and polymerization, including routes to cyclopentanone and cyclopentanol.

Packaging, Documents and Ordering

  • Regular orders ship in 50 kg blue plastic drums or 150 kg and 200 kg steel drums, and ISO tank shipments can be arranged for large volumes, matching the photos. Keep the liquid sealed and cool, away from heat and flame because of the very low flash point.
  • As a flammable liquid (UN 1146), every lot comes with a COA, TDS and SDS, with assay and impurities on the COA and emergency advice on the SDS.
  • Samples are available for evaluation. To quote, UATChem needs the grade, quantity, packing and destination port.

FAQ

Q: What is cyclopentane used for?

A: Cyclopentane is a blowing agent for rigid polyurethane foam in refrigerators, panels and spray foam, and also a solvent.
