Beschreibung
N-Methyl-2-pyrrolidone is a high-purity polar aprotic solvent supplied at min. 99,8 % for synthesis applications. With the empirical formula C₅H₉NO, CAS number 872-50-4 and EG nr. 212-828-1, it offers a molar mass of 99,13 g/mol and a density of 1,03 g/cm³. The boiling point is 204,3 °C and the flash point is 91 °C, supporting controlled use in organic synthesis, polymer processing and laboratory work where a stable, high-boiling amide solvent is required. This grade is N-Methyl-2-pyrrolidone (NMP) is widely employed as a reaction medium, extraction solvent and process aid thanks to its strong solvating power for both organic and inorganic materials. Material from manufacturer Carl ROTH meets the stated synthesis specification and is suitable for routine preparative chemistry. Physical constants such as density and boiling range help laboratories verify identity and plan safe heating and distillation steps. The glass bottle format supports accurate dispensing and storage of this versatile cyclic amide solvent in research and industrial laboratories.

Questions about N-Methyl-2-pyrrolidone, min. 99,8 %, for synthesis, 500 ml, glass
What is this article?
N-Methyl-2-pyrrolidone, min. 99,8 %, for synthesis, 500 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Labor- und Industriechemikalien.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
