The occurrence of 81154-02-1 (5E)-5-[(3-Methoxyphenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one DTXSID60364357 is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
81154-02-1 (5E)-5-[(3-Methoxyphenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one DTXSID60364357 (CAS 81154-02-1), molecular formula C11H9NO2S2 and molecular weight 251.32 g/mol, is a CATO reference standard with documented purity and traceability.
81154-02-1 (5E)-5-[(3-Methoxyphenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one DTXSID60364357 (C11H9NO2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
CATO manufactures 81154-02-1 (5E)-5-[(3-Methoxyphenyl)methylidene]-2-sulfanylidene-1,3-thiazolidin-4-one DTXSID60364357 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.
