Description
Methanol ROTIPURAN® min. 99,9 %, p.a., ACS, ISO is a high-purity laboratory solvent with CAS number 67-56-1 and empirical formula CH₃OH. 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. Supplied in a 1 l glass bottle, this grade meets p.a., ACS and ISO specifications for analytical chemistry, sample preparation and general solvent use. Minimum 99,9 % purity supports extractions, chromatography workflows and routine wet-chemical procedures that demand a defined analytical quality. This methanol from manufacturer Carl ROTH is part of the ROTIPURAN® line for reproducible results under quality-controlled laboratory conditions. Polar protic solvent behaviour makes it suitable as a reaction and dissolution medium across organic and inorganic methods. The product carries EG number 200-659-6 and UN number 1230. The one-litre glass pack offers a practical volume for bench-scale analysis, method development and ongoing solvent supply in research and industrial laboratories specifying ACS- and ISO-aligned methanol.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Methanol ROTIPURAN® min. 99,9 %, p.a., ACS, ISO, 1 l glass
What is this article?
Methanol ROTIPURAN® min. 99,9 %, p.a., ACS, ISO, 1 l glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.
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 Solvants. The sub-category is Solvants de qualité analytique (p.a.). The catalogue is Produits chimiques.
Shelves beside this one are Solvants de qualité HPLC & LC-MS, Solvants secs & deutérés (NMR, synthèse), Solvants de qualité technique & synthèse and Solvants verts & alternatifs.
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.
