3,3-Dimethyl-1-(4-{[1,2,4]triazolo[1,5-a]pyrimidin-7-yl}phenyl)azetidin-2-one CAS 303985-90-2 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.

3,3-Dimethyl-1-(4-{[1,2,4]triazolo[1,5-a]pyrimidin-7-yl}phenyl)azetidin-2-one (CAS 303985-90-2) is a high-purity analytical reference standard with the molecular formula C16H15N5O and a molecular weight of 293.32 g/mol.

Based on its molecular formula C16H15N5O, 3,3-Dimethyl-1-(4-{[1,2,4]triazolo[1,5-a]pyrimidin-7-yl}phenyl)azetidin-2-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
