(5E)-2-Mercapto-5-(2-methylbenzylidene)-1,3-thiazol-4(5H)-one 4430AE 50459-52-4 C11H9NOS2 (CAS 50459-52-4) is a high-purity analytical reference standard with the molecular formula C11H9NOS2 and a molecular weight of 235.33 g/mol.
(5E)-2-Mercapto-5-(2-methylbenzylidene)-1,3-thiazol-4(5H)-one 4430AE 50459-52-4 C11H9NOS2 (C11H9NOS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
