2-((2-((2,6-Dichlorophenyl)amino)-2-oxoethyl)thio)acetic acid CAS 338421-32-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((2-((2,6-Dichlorophenyl)amino)-2-oxoethyl)thio)acetic acid.

CATO supplies 2-((2-((2,6-Dichlorophenyl)amino)-2-oxoethyl)thio)acetic acid (CAS 338421-32-2), a certified reference material (molecular formula C10H9Cl2NO3S, MW 294.15 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-((2-((2,6-Dichlorophenyl)amino)-2-oxoethyl)thio)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
