(E)-3-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)-N-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)vinyl)aniline (CAS 303997-79-7) is a high-purity analytical reference standard with the molecular formula C20H11Cl2F6N3O and a molecular weight of 494.22 g/mol.
The molecular framework of (E)-3-((3-chloro-5-(trifluoromethyl)pyridin-2-yl)oxy)-N-(2-(3-chloro-5-(trifluoromethyl)pyridin-2-yl)vinyl)aniline (C20H11Cl2F6N3O) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
