Chemical Structure
Description
As a certified reference material (CRM), 2-(3-Nitrophenyl)nicotinic 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.
2-(3-Nitrophenyl)nicotinic acid (CAS 937601-72-4) is a high-purity analytical reference standard with the molecular formula C12H8N2O4 and a molecular weight of 244.20 g/mol.
The molecular framework of 2-(3-Nitrophenyl)nicotinic acid (C12H8N2O4) 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.
