CATO supplies 5-((3-(4-Bromophenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-(sec-butyl)-2-thioxothiazolidin-4-one (CAS 623933-14-2), a certified reference material (molecular formula C23H20BrN3OS2, MW 498.46 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 5-((3-(4-Bromophenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-3-(sec-butyl)-2-thioxothiazolidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes ā including a molecular weight of 498.46 g/mol ā 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.
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.
