Chemical Structure

9-Methyl-2-(methylthio)-5H-thiochromeno[4,3-d]pyrimidine CAS 478246-76-3 chemical structure

Description

As a certified reference material (CRM), 9-Methyl-2-(methylthio)-5H-thiochromeno[4,3-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.

CATO supplies 9-Methyl-2-(methylthio)-5H-thiochromeno[4,3-d]pyrimidine (CAS 478246-76-3), a certified reference material (molecular formula C13H12N2S2, MW 260.38 g/mol) for analytical method development and quality control.

9-Methyl-2-(methylthio)-5H-thiochromeno[4,3-d]pyrimidine (C13H12N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
