Chemical Structure

N-Acetyl-S-(2-carbamoylethyl-d4)-L-cysteine CAS CATO-CCAD302168 chemical structure

Description

The occurrence of N-Acetyl-S-(2-carbamoylethyl-d4)-L-cysteine is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Acetyl-S-(2-carbamoylethyl-d4)-L-cysteine (CAS CATO-CCAD302168), molecular formula C8H10D4N2O4S and molecular weight 238.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-Acetyl-S-(2-carbamoylethyl-d4)-L-cysteine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.30 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.

As a certified reference material (CRM), N-Acetyl-S-(2-carbamoylethyl-d4)-L-cysteine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
