n-Heptane 95% for HPLC is a high-purity, linear alkane solvent primarily used in high-performance liquid chromatography (HPLC) for separating and analyzing non-polar compounds. It also serves as a reference standard in gas chromatography and a solvent in laboratory applications requiring low polarity and high purity. Beyond chromatography, n-heptane is the zero-octane reference standard for octane-rating and engine knock testing, and is used in organic synthesis and preparing laboratory reagents. This product has a CAS number of 142-82-5, molecular formula CH3(CH2)5CH3, and a molecular weight of 100.20 g/mol. It is stored at ambient conditions and carries a signal word of "Danger" due to its flammable nature. Molekula supplies n-Heptane 95% for HPLC from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
