Compared with other compounds in its class, the molecular weight of 280.35 g/mol gives 2-(2,7-Dimethyl-5H-pyrimido[4,5-d]thiazolo[3,2-a]pyrimidin-8-yl)ethan-1-ol dihydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(2,7-Dimethyl-5H-pyrimido[4,5-d]thiazolo[3,2-a]pyrimidin-8-yl)ethan-1-ol dihydrate (CAS 51827-51-1), a certified reference material (molecular formula C12H14N4OSH2O, MW 280.35 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2,7-Dimethyl-5H-pyrimido[4,5-d]thiazolo[3,2-a]pyrimidin-8-yl)ethan-1-ol dihydrate (C12H14N4OSH2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
