Chemical Structure
Description
The occurrence of (Z)-(2-(benzo[d][1,3]dioxol-5-yl)cyclopropyl)(4-chloro-3-nitrophenyl)methanone O-(2,4-dichlorobenzyl) oxime is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Z)-(2-(benzo[d][1,3]dioxol-5-yl)cyclopropyl)(4-chloro-3-nitrophenyl)methanone O-(2,4-dichlorobenzyl) oxime (CAS 338749-00-1) is a high-purity analytical reference standard with the molecular formula C24H17Cl3N2O5 and a molecular weight of 519.76 g/mol.
The molecular framework of (Z)-(2-(benzo[d][1,3]dioxol-5-yl)cyclopropyl)(4-chloro-3-nitrophenyl)methanone O-(2,4-dichlorobenzyl) oxime (C24H17Cl3N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
