7,9-Dimethylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(1H)-one CAS 55023-35-3

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.

CATO supplies 7,9-Dimethylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(1H)-one (CAS 55023-35-3), a certified reference material (molecular formula C11H9N3OS, MW 231.27 g/mol) for analytical method development and quality control.

7,9-Dimethylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(1H)-one (C11H9N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), 7,9-Dimethylpyrido[3',2':4,5]thieno[3,2-d]pyrimidin-4(1H)-one 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.
