Description

Compared with other compounds in its class, the molecular weight of 329.80 g/mol gives 5-Chloro-2-(methylthio)-N-(naphthalen-1-yl)pyrimidine-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Chloro-2-(methylthio)-N-(naphthalen-1-yl)pyrimidine-4-carboxamide (CAS 325725-31-3) is a high-purity analytical reference standard with the molecular formula C16H12ClN3OS and a molecular weight of 329.80 g/mol.

5-Chloro-2-(methylthio)-N-(naphthalen-1-yl)pyrimidine-4-carboxamide (C16H12ClN3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 5-Chloro-2-(methylthio)-N-(naphthalen-1-yl)pyrimidine-4-carboxamide 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.
