Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-(1-Methyl-1h-pyrazol-4-yl)-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid (CAS 1490858-72-4), molecular formula C9H8N4O3 and molecular weight 220.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(1-Methyl-1h-pyrazol-4-yl)-6-oxo-1,6-dihydropyrimidine-5-carboxylic acid (C9H8N4O3) 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.
