Description
CATO manufactures 4-Amino-3-hydroxy-5-nitrobenzoic acid 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.
4-Amino-3-hydroxy-5-nitrobenzoic acid (CAS 1394916-93-8), molecular formula C7H6N2O5 and molecular weight 198.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Amino-3-hydroxy-5-nitrobenzoic acid (C7H6N2O5) is characterized by an amino-acid-derived structure, an amide 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. 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.
