Description
Methanol ROTISOLV® HPLC Grade is a chromatography-oriented solvent supplied for liquid chromatography applications. It corresponds to CAS number 67-56-1, empirical formula CH₃OH, molar mass 32,04 g/mol and density 0,79 g/cm³. Reported physical properties include a flash point of 9,7 °C and a boiling point of 65 °C, which inform handling and method conditions in HPLC laboratories. The product is delivered in a 2,5 l glass bottle, a practical pack size for preparing mobile phases and rinsing systems in routine LC and HPLC work. Available from manufacturer Carl ROTH under the ROTISOLV® HPLC Grade line, this methanol supports analytical workflows that rely on consistent solvent performance. It is used where methanol is specified as eluent component, diluent, or system solvent in liquid chromatography. Glass packaging helps maintain product integrity during storage and dispensing in chromatography laboratories engaged in separation science and related analytical tasks.

Questions about Methanol, ROTISOLV® HPLC Grade, 2.5 l, glass
What is this article?
Methanol, ROTISOLV® HPLC Grade, 2.5 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
