Chemical Structure
Description
The molecular framework of (Z)-(2-(4-chlorophenyl)cyclopropyl)(4-nitrophenyl)methanone O-(2,4-dichlorobenzyl) oxime (C23H17Cl3N2O3) is characterized by a steroid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(Z)-(2-(4-chlorophenyl)cyclopropyl)(4-nitrophenyl)methanone O-(2,4-dichlorobenzyl) oxime (CAS 338401-35-7), molecular formula C23H17Cl3N2O3 and molecular weight 475.75 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
