Description
Compared with other compounds in its class, the molecular weight of 349.76 g/mol gives (5Z)-5-{[2-(4-chloro-3-fluorophenoxy)phenyl]methylidene}-1,3-thiazolidine-2,4-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5Z)-5-{[2-(4-chloro-3-fluorophenoxy)phenyl]methylidene}-1,3-thiazolidine-2,4-dione (CAS 917602-19-8), molecular formula C16H9ClFNO3S and molecular weight 349.76 g/mol, is a CATO reference standard with documented purity and traceability.
(5Z)-5-{[2-(4-chloro-3-fluorophenoxy)phenyl]methylidene}-1,3-thiazolidine-2,4-dione (C16H9ClFNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (5Z)-5-{[2-(4-chloro-3-fluorophenoxy)phenyl]methylidene}-1,3-thiazolidine-2,4-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
