Compared with other compounds in its class, the molecular weight of 183.23 g/mol gives 2-((4-Methylpyrimidin-2-yl)thio)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((4-Methylpyrimidin-2-yl)thio)acetamide (CAS 74537-76-1) is a high-purity analytical reference standard with the molecular formula C7H9N3OS and a molecular weight of 183.23 g/mol.
The molecular framework of 2-((4-Methylpyrimidin-2-yl)thio)acetamide (C7H9N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 2-((4-Methylpyrimidin-2-yl)thio)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
