Chemical Structure
Description
As a certified reference material (CRM), 3-Nitropyridine-2-carboxylic Acid 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.
CATO supplies 3-Nitropyridine-2-carboxylic Acid (CAS 59290-85-6), a certified reference material (molecular formula C6H4N2O4, MW 168.11 g/mol) for analytical method development and quality control.
The molecular framework of 3-Nitropyridine-2-carboxylic Acid (C6H4N2O4) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
