N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine CAS 131685-10-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine.

N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine (CAS 131685-10-4), molecular formula C7H9D3N2O4S and molecular weight 223.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine (C7H9D3N2O4S) is characterized by deuterium isotope labeling, an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures N-Acetyl-d3-S-(N-methylcarbamoyl)-L-cysteine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
