Chemical Structure

N-Methyl-d3-ε-caprolactam CAS 203645-60-7 chemical structure

Description

CATO supplies N-Methyl-d3-ε-caprolactam (CAS 203645-60-7), a certified reference material (molecular formula C7H10D3NO, MW 130.20 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage, N-Methyl-d3-ε-caprolactam is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
