1-Ethyl-2-Pyrrolidone-d5 CAS CATO-C3D-25881 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 1-Ethyl-2-Pyrrolidone-d5 (CAS CATO-C3D-25881), a certified reference material (molecular formula C6H6D5NO, MW 118.19 g/mol) for analytical method development and quality control.

1-Ethyl-2-Pyrrolidone-d5 (C6H6D5NO) contains deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
