Chemical Structure

N-Acetyl-S-(2-hydroxyethyl)-L-cysteine Sodium SaltDiscontinued See: A178911 CAS 84608-41-3 chemical structure

Description

The occurrence of N-Acetyl-S-(2-hydroxyethyl)-L-cysteine Sodium SaltDiscontinued See: A178911 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Acetyl-S-(2-hydroxyethyl)-L-cysteine Sodium SaltDiscontinued See: A178911 (CAS 84608-41-3) is a high-purity analytical reference standard with the molecular formula C7H12NNaO4S and a molecular weight of 229.23 g/mol.

The molecular framework of N-Acetyl-S-(2-hydroxyethyl)-L-cysteine Sodium SaltDiscontinued See: A178911 (C7H12NNaO4S) 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.

As a certified reference material (CRM), N-Acetyl-S-(2-hydroxyethyl)-L-cysteine Sodium SaltDiscontinued See: A178911 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.
