(5E)-3-[(4-tert-Butylphenyl)methyl]-5-{[3-(trifluoromethyl)phenyl]methylidene}-1,3-thiazolidine-2,4-dione (CAS 866152-71-8), molecular formula C22H20F3NO2S and molecular weight 419.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, (5E)-3-[(4-tert-Butylphenyl)methyl]-5-{[3-(trifluoromethyl)phenyl]methylidene}-1,3-thiazolidine-2,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (5E)-3-[(4-tert-Butylphenyl)methyl]-5-{[3-(trifluoromethyl)phenyl]methylidene}-1,3-thiazolidine-2,4-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
