N-(5-(1-Isopropyl-1H-pyrazol-5-yl)-1,3,4-oxadiazol-2-yl)-2-phenylacetamide CAS 1172072-03-5

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.

N-(5-(1-Isopropyl-1H-pyrazol-5-yl)-1,3,4-oxadiazol-2-yl)-2-phenylacetamide (CAS 1172072-03-5) is a high-purity analytical reference standard with the molecular formula C16H17N5O2 and a molecular weight of 311.34 g/mol.

The molecular framework of N-(5-(1-Isopropyl-1H-pyrazol-5-yl)-1,3,4-oxadiazol-2-yl)-2-phenylacetamide (C16H17N5O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. 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.
