Description
Methanol ROTISOLV® min. 99,9 %. HPLC is a high-purity solvent intended for liquid chromatography and related analytical work. With CAS number 67-56-1, empirical formula CH₃OH and molar mass 32,04 g/mol, it meets demanding HPLC-grade requirements for mobile-phase preparation and sample handling. Key physical properties include a density of 0,79 g/cm³, flash point 9,7 °C and boiling point 65 °C; the EG number is 200-659-6. The product is Offered by manufacturer Carl ROTH within the ROTISOLV® line, this methanol is positioned for laboratories that need a defined minimum assay of 99,9 % for HPLC. Typical uses include reverse-phase and normal-phase liquid chromatography, solvent blending, and analytical sample work-up where a consistent, high-purity alcohol matrix is essential.

Questions about Methanol, ROTISOLV® min. 99.9 % HPLC , 2.5 l, glass
What is this article?
Methanol, ROTISOLV® min. 99.9 % HPLC , 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.
