Heptane 95% SG is a straight-chain alkane solvent (C7H16) widely used in laboratory analysis, chromatography, and industrial cleaning due to its low polarity and high volatility. It serves as a reference standard for GC-MS calibration, a degreasing agent, and a solvent for extracting non-polar compounds. It is also the zero-octane reference fuel for octane-rating and engine knock testing, and is used in organic synthesis and laboratory reagent preparation. This product has a CAS number of 142-82-5, a molecular weight of 100.20 g/mol, and is stored at ambient conditions. The signal word is "Danger," indicating hazardous properties. Molekula supplies Heptane 95% SG from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
