Description
Compared with other compounds in its class, the molecular weight of 521.80 g/mol gives (5E)-1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-5-({[3-(trifluoromethyl)phenyl]amino}methylidene)-1,3-diazinane-2,4,6-trione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5E)-1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-5-({[3-(trifluoromethyl)phenyl]amino}methylidene)-1,3-diazinane-2,4,6-trione (CAS 306978-02-9) is a high-purity analytical reference standard with the molecular formula C20H14ClF6N5O3 and a molecular weight of 521.80 g/mol.
The molecular framework of (5E)-1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-5-({[3-(trifluoromethyl)phenyl]amino}methylidene)-1,3-diazinane-2,4,6-trione (C20H14ClF6N5O3) 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 the protonation state of its nitrogen-containing groups, 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.
