(2R)-2-(carbamoylamino)-3-sulfanylpropanoic acid 24583-23-1 CHEBI:64855 L-Cysteine-N-carbamide L-NCC N-(Aminocarbonyl)cysteine N-carbamoyl-L-cysteine CAS 24583-23-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R)-2-(carbamoylamino)-3-sulfanylpropanoic acid 24583-23-1 CHEBI:64855 L-Cysteine-N-carbamide L-NCC N-(Aminocarbonyl)cysteine N-carbamoyl-L-cysteine.

CATO supplies (2R)-2-(carbamoylamino)-3-sulfanylpropanoic acid 24583-23-1 CHEBI:64855 L-Cysteine-N-carbamide L-NCC N-(Aminocarbonyl)cysteine N-carbamoyl-L-cysteine (CAS 24583-23-1), a certified reference material (molecular formula C4H8N2O3S, MW 164.18 g/mol) for analytical method development and quality control.

The molecular framework of (2R)-2-(carbamoylamino)-3-sulfanylpropanoic acid 24583-23-1 CHEBI:64855 L-Cysteine-N-carbamide L-NCC N-(Aminocarbonyl)cysteine N-carbamoyl-L-cysteine (C4H8N2O3S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

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.
