Description
Methanol ROTIPURAN® min. 99,8 %, p.a. is an analytical-grade solvent intended for laboratory applications that require a defined high purity. It is identified by CAS number 67-56-1 and EG nr. 200-659-6, with the empirical formula CH₃OH and a molar mass of 32,04 g/mol. 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, which support safe storage planning and method documentation. The product is a.) category used across chemical and analytical laboratories. With a minimum assay of 99,8 %, this methanol grade is suitable for sample preparation, rinsing steps and general solvent use where p.a. quality is specified. Offered by manufacturer Carl ROTH within the ROTIPURAN® range, provides a practical bench-scale volume for routine work. Laboratories specifying methanol for analytical protocols can reference the stated purity, formula and physicochemical data when aligning reagents with method requirements and internal quality systems.

Questions about Methanol, ROTIPURAN® min. 99,8 %, p.a., 1 l, plastic
What is this article?
Methanol, ROTIPURAN® min. 99,8 %, p.a., 1 l, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
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.
