n-Pentane ACS Reagent Grade
High-purity n-pentane (normal pentane, C5H12) meeting American Chemical Society standards for laboratory use in chromatography and extractions. It falls under HTS 2901.10.30.00 as a separate chemically defined saturated acyclic hydrocarbon. This isomer is distinguished from isopentane by its straight-chain structure.
