Description
Methanol, min. 99,5 %, VLSI Grade is a high-purity monohydric alcohol with the empirical formula CH₃OH, CAS number 67-56-1 and a molar mass of 32,04 g/mol. Reported properties include a density of 0,79 g/cm³, a flash point of 9,7 °C and a boiling point of 65 °C, supporting its role as a polar, fast-evaporating process and laboratory solvent. This VLSI Grade material is Methanol from manufacturer Carl ROTH is listed under EG nr. 200-659-6 and UN number 1230. It is used in cleaning, extraction support, sample preparation and related wet-chemical steps where a simple C₁ alcohol of controlled purity is specified. The combination of VLSI Grade designation, clear physicochemical data and practical pack size makes this methanol suitable for laboratories standardising solvent quality across analytical and process-oriented tasks.

Questions about Methanol, min. 99,5 %, VLSI Grade, 2.5 l, plastic
What is this article?
Methanol, min. 99,5 %, VLSI Grade, 2.5 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.
