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.

4-Chloro-2-((4-methylbenzyl)thio)-6-phenylpyrimidine-5-carbonitrile (CAS 860649-62-3), molecular formula C19H14ClN3S and molecular weight 351.85 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C19H14ClN3S, 4-Chloro-2-((4-methylbenzyl)thio)-6-phenylpyrimidine-5-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), 4-Chloro-2-((4-methylbenzyl)thio)-6-phenylpyrimidine-5-carbonitrile 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.
