3-{[(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)amino]methylidene}-1,1,1,5,5,5-hexafluoropentane-2,4-dione CAS 339099-76-2

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.

CATO supplies 3-{[(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)amino]methylidene}-1,1,1,5,5,5-hexafluoropentane-2,4-dione (CAS 339099-76-2), a certified reference material (molecular formula C18H8ClF9N2O3, MW 506.71 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-{[(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)amino]methylidene}-1,1,1,5,5,5-hexafluoropentane-2,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 506.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 3-{[(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)amino]methylidene}-1,1,1,5,5,5-hexafluoropentane-2,4-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
