Description
CATO supplies (4-(1H-Pyrazol-1-yl)phenyl)(4-((3,4-dihydro-2H-benzo[b][1,4]dioxepin-7-yl)sulfonyl)piperazin-1-yl)methanone (CAS 956932-32-4), a certified reference material (molecular formula C23H24N4O5S, MW 468.53 g/mol) for analytical method development and quality control.
The molecular framework of (4-(1H-Pyrazol-1-yl)phenyl)(4-((3,4-dihydro-2H-benzo[b][1,4]dioxepin-7-yl)sulfonyl)piperazin-1-yl)methanone (C23H24N4O5S) is characterized by a flavonoid core, an amide group, a sulfone 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.
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.
