Description
Methanol ROTISOLV®, min. 99,95 %. HPLC Ultra Gradient Grade, is a high-purity chromatographic solvent With CAS number 67-56-1, empirical formula CH₃OH, molar mass 32,04 g/mol and EG number 200-659-6, it is specified for HPLC ultra gradient applications in analytical and environmental laboratories. Key physical properties include a density of 0,79 g/cm³, a flash point of 9,7 °C and a boiling point of 65 °C; the UN number is 1230. This grade from manufacturer Carl ROTH is intended for liquid chromatography and related separation methods where a minimum assay of 99,95 % supports low-background gradient performance. The one-litre glass pack is practical for routine HPLC solvent supply on the bench or in solvent cabinets. Typical use spans environmental analysis and liquid chromatography workflows that require consistent methanol quality for mobile-phase preparation, sample dilution and system flushing under ultra gradient conditions.
This article is part of HPLC & LC-MS grade solvents, in Solvents. See also Analytical grade solvents (p.a.).

Questions about Methanol ROTISOLV®, , min. 99,95 % HPLC Ultra Gradient Grade, 1 l, glass
What is this article?
Methanol ROTISOLV®, , min. 99,95 % HPLC Ultra Gradient Grade, 1 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.
