6-{2-methylpyrazolo[1,5-a]pyrimidin-7-yl}-2H,3H,5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one CAS 691868-59-4

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 6-{2-methylpyrazolo[1,5-a]pyrimidin-7-yl}-2H,3H,5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (CAS 691868-59-4), a certified reference material (molecular formula C13H11N5OS, MW 285.32 g/mol) for analytical method development and quality control.

Structurally, 6-{2-methylpyrazolo[1,5-a]pyrimidin-7-yl}-2H,3H,5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (C13H11N5OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 285.32 g/mol, it falls into the medium-molecular-weight range. 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).

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.
