(5Z)-5-[(4-Oxo-4H-chromen-3-yl)methylidene]-2-sulfanylidene-3-[(thiomorpholin-4-yl)methyl]imidazolidin-4-one (CAS 865659-99-0), molecular formula C18H17N3O3S2 and molecular weight 387.48 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (5Z)-5-[(4-Oxo-4H-chromen-3-yl)methylidene]-2-sulfanylidene-3-[(thiomorpholin-4-yl)methyl]imidazolidin-4-one (C18H17N3O3S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 387.48 g/mol, it falls into the moderately-high-molecular-weight range. 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-Oxo-4H-chromen-3-yl)methylidene]-2-sulfanylidene-3-[(thiomorpholin-4-yl)methyl]imidazolidin-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.
