(5Z)-5-[(4-Methoxyphenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one (CAS 478246-93-4), molecular formula C15H12O2S2 and molecular weight 288.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (5Z)-5-[(4-Methoxyphenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one (C15H12O2S2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures (5Z)-5-[(4-Methoxyphenyl)methylidene]-4H,5H,6H-thieno[2,3-b]thiopyran-4-one 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.
