Chemical Structure

2-Amino-4-(2-aminophenyl)-4-oxobutanoic acid compound with sulfuric acid (1:1) hydrate CAS 208653-85-4 chemical structure

Description

2-Amino-4-(2-aminophenyl)-4-oxobutanoic acid compound with sulfuric acid (1:1) hydrate (CAS 208653-85-4) is a high-purity analytical reference standard with the molecular formula C10H12N2O3H2O4SH2O and a molecular weight of 324.30 g/mol.

The molecular framework of 2-Amino-4-(2-aminophenyl)-4-oxobutanoic acid compound with sulfuric acid (1:1) hydrate (C10H12N2O3H2O4SH2O) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 2-Amino-4-(2-aminophenyl)-4-oxobutanoic acid compound with sulfuric acid (1:1) hydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
