Description

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.

1171087-88-9 1-(4-Nitrophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid MFCD14281946 (CAS 1171087-88-9), molecular formula C12H8N2O5 and molecular weight 260.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1171087-88-9 1-(4-Nitrophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid MFCD14281946 (C12H8N2O5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), 1171087-88-9 1-(4-Nitrophenyl)-6-oxo-1,6-dihydropyridine-3-carboxylic acid MFCD14281946 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.
