Chemical Structure

6-Methyl-5H-thiazolo[3,2-a]pyrimidin-5-one CAS 511540-51-5 chemical structure

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-Methyl-5H-thiazolo[3,2-a]pyrimidin-5-one (CAS 511540-51-5), a certified reference material (molecular formula C7H6N2OS, MW 166.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H6N2OS, 6-Methyl-5H-thiazolo[3,2-a]pyrimidin-5-one contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 166.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
