Description

3-[(4-oxo-1,4-dihydro-2-pyrimidinyl)amino]benzoic acid 944795-45-3 (CAS 944795-45-3), molecular formula C11H9N3O3 and molecular weight 231.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-[(4-oxo-1,4-dihydro-2-pyrimidinyl)amino]benzoic acid 944795-45-3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 3-[(4-oxo-1,4-dihydro-2-pyrimidinyl)amino]benzoic acid 944795-45-3 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.
