Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(2,5-Dimethylphenyl)sulfanyl]-2-phenylpyrimidine-5-carboxylic acid.
4-[(2,5-Dimethylphenyl)sulfanyl]-2-phenylpyrimidine-5-carboxylic acid (CAS 1797376-50-1), molecular formula C19H16N2O2S and molecular weight 336.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-[(2,5-Dimethylphenyl)sulfanyl]-2-phenylpyrimidine-5-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.41 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), 4-[(2,5-Dimethylphenyl)sulfanyl]-2-phenylpyrimidine-5-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.
