Chemical Structure
Description
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.
(2Z)-N-(3,5-Dichlorophenyl)-3-(naphthalen-1-yl)prop-2-enamide (CAS 327068-62-2) is a high-purity analytical reference standard with the molecular formula C19H13Cl2NO and a molecular weight of 342.22 g/mol.
Based on its molecular formula C19H13Cl2NO, (2Z)-N-(3,5-Dichlorophenyl)-3-(naphthalen-1-yl)prop-2-enamide contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
