3-(2-Hydroxy-5,7-dimethyl-3-phenylpyrazolo[1,5-a]pyrimidin-6-yl)propanoic acid CAS 1245569-50-9

Description

CATO supplies 3-(2-Hydroxy-5,7-dimethyl-3-phenylpyrazolo[1,5-a]pyrimidin-6-yl)propanoic acid (CAS 1245569-50-9), a certified reference material (molecular formula C17H17N3O3, MW 311.34 g/mol) for analytical method development and quality control.

Based on its molecular formula C17H17N3O3, 3-(2-Hydroxy-5,7-dimethyl-3-phenylpyrazolo[1,5-a]pyrimidin-6-yl)propanoic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.34 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.

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.

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.
