Description
N-Methyl-2-pyrrolidone PEPTIPURE® is a high-purity solvent graded min. 99.8 % for peptide synthesis. Identified by CAS number 872-50-4 and empirical formula C₅H₉NO, it has a molar mass of 99,13 g/mol, a density of 1,03 g/cm³, a flash point of 91 °C and a boiling point of 204,3 °C. The EG number is 212-828-1. Supplied in a 2,5 l pack, this PEPTIPURE® quality material supports washing, deprotection and related steps in peptide chemistry where a defined N-methyl-2-pyrrolidone grade is specified. Available from manufacturer Carl ROTH, it is intended for laboratories performing solid-phase and solution-phase peptide synthesis that require a consistent organic solvent of documented purity. Physical parameters such as density and boiling point aid process planning and safe handling under standard laboratory controls. The min. 99.8 % specification aligns with demanding synthetic workflows. Packaged as 2,5 l, N-Methyl-2-pyrrolidone PEPTIPURE® offers a practical volume for repeated peptide synthesis operations in research and production-support environments.

Questions about N-Methyl-2-pyrrolidone, PEPTIPURE®, min. 99.8 %, for peptide synthesis, 2.5 l
What is this article?
N-Methyl-2-pyrrolidone, PEPTIPURE®, min. 99.8 %, for peptide synthesis, 2.5 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
