Compared with other compounds in its class, the molecular weight of 442.31 g/mol gives (Z)-[(4-Fluorophenyl)[2-(4-methylphenyl)cyclopropyl]methylidene]amino 3,4-dichlorobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(Z)-[(4-Fluorophenyl)[2-(4-methylphenyl)cyclopropyl]methylidene]amino 3,4-dichlorobenzoate (CAS 338749-07-8) is a high-purity analytical reference standard with the molecular formula C24H18Cl2FNO2 and a molecular weight of 442.31 g/mol.
The molecular framework of (Z)-[(4-Fluorophenyl)[2-(4-methylphenyl)cyclopropyl]methylidene]amino 3,4-dichlorobenzoate (C24H18Cl2FNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
