n-Heptane, ROTISOLV® min. 99 %, HPLC, 2.5 l, glass

n-Heptane is a straight-chain aliphatic hydrocarbon solvent supplied as ROTISOLV® grade with a minimum purity of 99 % and specified for HPLC use. Identified by CAS number 142-82-5 and EG number 205-563-8, it has the empirical formula C₇H₁₆ and a molar mass of 100,20 g/mol. Density lies between 0,68 and 0,69 g/cm³, the boiling range is 98,2 to 98,4 °C, and the flash point is −4 °C. This preparation is offered in a 2,5 l glass bottle, giving a convenient bulk volume for chromatographic mobile-phase preparation, sample dilution and general laboratory extraction work where a defined high-purity n-alkane is required. The product is available from manufacturer Carl ROTH under the ROTISOLV® HPLC line, supporting reproducible solvent performance in analytical and preparative workflows. UN number 1206 applies for transport classification. With its narrow boiling interval and controlled density, the solvent is well suited to methods that demand consistent elution strength and low background contribution in HPLC systems.
