Chemical Structure
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.
6-Methyl-2-(methylthio)pyrimidine-4-carbonitrile (CAS 65735-62-8) is a high-purity analytical reference standard with the molecular formula C7H7N3S and a molecular weight of 165.22 g/mol.
The molecular framework of 6-Methyl-2-(methylthio)pyrimidine-4-carbonitrile (C7H7N3S) is characterized by a nitrile group, sulfur-containing functionality, 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).
CATO manufactures 6-Methyl-2-(methylthio)pyrimidine-4-carbonitrile 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.
