CATO supplies 6-Ethyl-7-imino-2,4-dimethyl-6,7-dihydrooxazolo[5,4-d]pyrimidine-5(4H)-thione (CAS 698365-69-4), a certified reference material (molecular formula C9H12N4OS, MW 224.28 g/mol) for analytical method development and quality control.

The molecular framework of 6-Ethyl-7-imino-2,4-dimethyl-6,7-dihydrooxazolo[5,4-d]pyrimidine-5(4H)-thione (C9H12N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
