The occurrence of (4Z)-4-({[2-chloro-5-(trifluoromethyl)phenyl]amino}methylidene)-2-[(2,4-dichlorophenyl)methoxy]-1,2,3,4-tetrahydroisoquinoline-1,3-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (4Z)-4-({[2-chloro-5-(trifluoromethyl)phenyl]amino}methylidene)-2-[(2,4-dichlorophenyl)methoxy]-1,2,3,4-tetrahydroisoquinoline-1,3-dione (CAS 338396-47-7), a certified reference material (molecular formula C24H14Cl3F3N2O3, MW 541.73 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, (4Z)-4-({[2-chloro-5-(trifluoromethyl)phenyl]amino}methylidene)-2-[(2,4-dichlorophenyl)methoxy]-1,2,3,4-tetrahydroisoquinoline-1,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 541.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
