Methanol ROTISOLV® is a high-purity solvent graded at minimum 99,9 % for LC-MS use. It carries CAS number 67-56-1 and EG number 200-659-6, with empirical formula CH₃OH and a molar mass of 32,04 g/mol. Reported physical data include a density of 0,79 g/cm³, a flash point of 9,7 °C and a boiling point of 65 °C. Delivered in a 2,5 l glass bottle from manufacturer Carl ROTH, this methanol belongs to the solvent range intended for chromatographic applications and LC-MS. Laboratories employ LC-MS-grade methanol as a mobile-phase constituent, diluent and rinse solvent where high chemical purity supports sensitive mass-spectrometric detection and reproducible chromatography. UN number 1230 applies to transport classification. Handle as a flammable liquid under standard laboratory controls. This ROTISOLV® quality offers a well-defined methanol option for LC-MS and related analytical workflows requiring consistent solvent performance.
