4-[(4-Methylphenyl)sulfanyl]-2-(methylsulfanyl)thieno[3,2-d]pyrimidine CAS 866049-12-9

Description

4-[(4-Methylphenyl)sulfanyl]-2-(methylsulfanyl)thieno[3,2-d]pyrimidine (CAS 866049-12-9), molecular formula C14H12N2S3 and molecular weight 304.45 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H12N2S3, 4-[(4-Methylphenyl)sulfanyl]-2-(methylsulfanyl)thieno[3,2-d]pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 304.45 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.

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-[(4-Methylphenyl)sulfanyl]-2-(methylsulfanyl)thieno[3,2-d]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.
