4-((3,4-Dichlorophenyl)thio)-5-methoxy-2-(methylthio)pyrimidine CAS 338955-64-9

Description

Compared with other compounds in its class, the molecular weight of 333.26 g/mol gives 4-((3,4-Dichlorophenyl)thio)-5-methoxy-2-(methylthio)pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-((3,4-Dichlorophenyl)thio)-5-methoxy-2-(methylthio)pyrimidine (CAS 338955-64-9), molecular formula C12H10Cl2N2OS2 and molecular weight 333.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 4-((3,4-Dichlorophenyl)thio)-5-methoxy-2-(methylthio)pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-((3,4-Dichlorophenyl)thio)-5-methoxy-2-(methylthio)pyrimidine 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.
