Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Furan-2-ylmethyl)-5-((1-phenyl-3-(p-tolyl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-4-one.
3-(Furan-2-ylmethyl)-5-((1-phenyl-3-(p-tolyl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-4-one (CAS 313362-43-5), molecular formula C25H19N3O2S2 and molecular weight 457.57 g/mol, is a CATO reference standard with documented purity and traceability.
3-(Furan-2-ylmethyl)-5-((1-phenyl-3-(p-tolyl)-1H-pyrazol-4-yl)methylene)-2-thioxothiazolidin-4-one (C25H19N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
