(E,Z)-1-Bromo-1,2-diphenyl-2-(4-hydroxyphenyl)ethene 4-(2-Bromo-1,2-diphenylethenyl)phenol 874504-11-7 |A'-Bromo-|A-phenyl-4-stilbenol (CAS 874504-11-7), molecular formula C20H15BrO and molecular weight 351.24 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (E,Z)-1-Bromo-1,2-diphenyl-2-(4-hydroxyphenyl)ethene 4-(2-Bromo-1,2-diphenylethenyl)phenol 874504-11-7 |A'-Bromo-|A-phenyl-4-stilbenol (C20H15BrO) contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 351.24 g/mol, it falls into the moderately-high-molecular-weight range. 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.
