7-(4-Methoxyphenyl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridine-2,4-diol (CAS 497078-68-9) is a high-purity analytical reference standard with the molecular formula C18H11F3N2O3S and a molecular weight of 392.35 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 7-(4-Methoxyphenyl)-9-(trifluoromethyl)thieno[2,3-b:4,5-b']dipyridine-2,4-diol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.35 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.
