Heptane (CAS 142-82-5) is a non-polar straight-chain alkane supplied as a liquid with a color of no more than 10 APHA, used as the zero-point reference standard for octane rating tests, as a degreasing solvent for metal parts, and as a carrier for rubber cements. We supply High-Purity n-Heptane suitable for precision laboratory use and heavy industrial degreasing.
This Technical Grade hydrocarbon is essential for the automotive industry, serving as the standard for fuel "knock" testing. It offers Excellent Stability and low odor compared to aromatic solvents.
In manufacturing, it acts as a primary carrier for rubber cements and specialized adhesives. Its Consistent Quality ensures uniform drying times and high bond strength in rubber processing.
