Description

As a certified reference material (CRM), N-(2-Chloro-4,6-dimethylphenyl)-2-((3-ethyl-5,6-dimethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)acetamide 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.

N-(2-Chloro-4,6-dimethylphenyl)-2-((3-ethyl-5,6-dimethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)acetamide (CAS 579446-87-0), molecular formula C20H22ClN3O2S2 and molecular weight 435.99 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-(2-Chloro-4,6-dimethylphenyl)-2-((3-ethyl-5,6-dimethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl)thio)acetamide (C20H22ClN3O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
