Description
We manufacture n-Octane (CH₃(CH₂)₆CH₃, CAS 111-65-9) at 99% minimum purity, supplied in bulk ISO tank and drum packaging for industrial buyers. n-Octane is a straight-chain alkane widely used as a solvent and raw material in organic synthesis, and it plays an established role in fuel research, where isomers such as 2,2,4-trimethylpentane (isooctane) serve as reference points on the octane rating scale.
Beyond synthesis and fuel research, n-Octane is used as a solvent across the rubber and paper processing industries, where its low polarity and consistent evaporation profile support a range of processing steps.
