2-(3-Methylphenyl)-4-[3-(pyridin-3-yl)-1,2,4-oxadiazol-5-yl]-1,2-dihydrophthalazin-1-one CAS 1206992-20-2

Description

The molecular framework of 2-(3-Methylphenyl)-4-[3-(pyridin-3-yl)-1,2,4-oxadiazol-5-yl]-1,2-dihydrophthalazin-1-one (C22H15N5O2) is characterized by a steroid core, 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. 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).

CATO supplies 2-(3-Methylphenyl)-4-[3-(pyridin-3-yl)-1,2,4-oxadiazol-5-yl]-1,2-dihydrophthalazin-1-one (CAS 1206992-20-2), a certified reference material (molecular formula C22H15N5O2, MW 381.39 g/mol) for analytical method development and quality control.

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.
