Chemical Structure
Description
Based on its molecular formula C21H17ClO, (Z)-1-Chloro-4-(2-(4-methoxyphenyl)-2-phenylvinyl)benzene contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 320.81 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.
CATO supplies (Z)-1-Chloro-4-(2-(4-methoxyphenyl)-2-phenylvinyl)benzene (CAS 1503-60-2), a certified reference material (molecular formula C21H17ClO, MW 320.81 g/mol) for analytical method development and quality control.
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.
