2-[[(carboxymethylthio)-phenylmethyl]amino]benzoic acid 2-[[2-hydroxy-2-oxoethylsulfanyl(phenyl)methyl]amino]benzoic acid 923-42-2 A844204 CAS 923-42-2

Description

2-[[(carboxymethylthio)-phenylmethyl]amino]benzoic acid 2-[[2-hydroxy-2-oxoethylsulfanyl(phenyl)methyl]amino]benzoic acid 923-42-2 A844204 (CAS 923-42-2) is a high-purity analytical reference standard with the molecular formula C7H10O6 and a molecular weight of 190.15 g/mol.

2-[[(carboxymethylthio)-phenylmethyl]amino]benzoic acid 2-[[2-hydroxy-2-oxoethylsulfanyl(phenyl)methyl]amino]benzoic acid 923-42-2 A844204 (C7H10O6) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-[[(carboxymethylthio)-phenylmethyl]amino]benzoic acid 2-[[2-hydroxy-2-oxoethylsulfanyl(phenyl)methyl]amino]benzoic acid 923-42-2 A844204 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.
