CATO supplies 4-(5-((3-(3-Fluoro-4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-4-oxo-2-thioxothiazolidin-3-yl)butanoic acid (CAS 623936-17-4), a certified reference material (molecular formula C24H20FN3O3S2, MW 481.56 g/mol) for analytical method development and quality control.
4-(5-((3-(3-Fluoro-4-methylphenyl)-1-phenyl-1H-pyrazol-4-yl)methylene)-4-oxo-2-thioxothiazolidin-3-yl)butanoic acid (C24H20FN3O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
