Description
CATO manufactures 1-Hydroxy-2,7-naphthyridine-3-carboxylic 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.
1-Hydroxy-2,7-naphthyridine-3-carboxylic acid (CAS 42285-31-4), molecular formula C9H6N2O3 and molecular weight 190.16 g/mol, is a CATO reference standard with documented purity and traceability.
1-Hydroxy-2,7-naphthyridine-3-carboxylic acid (C9H6N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
