Chemical Structure
Description
N-(2-(3-(4-Chlorophenyl)-6-oxopyridazin-1(6H)-yl)ethyl)-2-(trifluoromethyl)benzamide (C20H15ClF3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
N-(2-(3-(4-Chlorophenyl)-6-oxopyridazin-1(6H)-yl)ethyl)-2-(trifluoromethyl)benzamide (CAS 921577-37-9) is a high-purity analytical reference standard with the molecular formula C20H15ClF3N3O2 and a molecular weight of 421.80 g/mol.
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.
