Chemical Structure
Description
The occurrence of (Z)-{2-[(4-chlorophenyl)sulfanyl]-1-phenylethylidene}[(2,4-dichlorophenyl)methoxy]amine is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(Z)-{2-[(4-chlorophenyl)sulfanyl]-1-phenylethylidene}[(2,4-dichlorophenyl)methoxy]amine (CAS 344268-48-0) is a high-purity analytical reference standard with the molecular formula C21H16Cl3NOS and a molecular weight of 436.78 g/mol.
The molecular framework of (Z)-{2-[(4-chlorophenyl)sulfanyl]-1-phenylethylidene}[(2,4-dichlorophenyl)methoxy]amine (C21H16Cl3NOS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
