Description
Methanol ROTISOLV® min. 99,9 % Pestilyse® plus is a high-purity solvent with the formula CH₃OH, CAS number 67-56-1 and EG number 200-659-6. It has a molar mass of 32,04 g/mol and a density of 0,79 g/cm³, with a boiling point of 65 °C and a flash point of 9,7 °C. This Pestilyse® plus quality is intended for chromatographic applications and gas chromatography where tightly controlled solvent purity is specified. Supplied in a 2,5 l glass bottle, the product supports laboratory solvent handling, elution and sample preparation. Physical parameters including density and boiling point aid method development for GC and related chromatographic work. Available from manufacturer Carl ROTH within the ROTISOLV® portfolio, the material addresses analytical solvent needs in research and routine laboratories. Transport classification references UN number 1230 for this flammable liquid. Laboratories can integrate the methanol into workflows that require min. 99,9 % assay for chromatographic reliability. Documented molar mass, density and thermal data support consistent solvent selection and reproducible analytical practice across diverse laboratory applications.

Questions about Methanol, ROTISOLV® min. 99,9 %, Pestilyse® plus, 2.5 l, glass
What is this article?
Methanol, ROTISOLV® min. 99,9 %, Pestilyse® plus, 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.
