Chemical Structure
Description
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.
(5E)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-fluorophenyl)methylidene]-1,3-thiazolidine-2,4-dione (CAS 866152-69-4) is a high-purity analytical reference standard with the molecular formula C21H20FNO2S and a molecular weight of 369.45 g/mol.
The molecular framework of (5E)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-fluorophenyl)methylidene]-1,3-thiazolidine-2,4-dione (C21H20FNO2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (5E)-3-[(4-tert-Butylphenyl)methyl]-5-[(4-fluorophenyl)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.
