(5E)-2-Mercapto-5-(mesitylmethylene)-1,3-thiazol-4(5H)-one 153567-97-6 4779AD C13H13NOS2 (CAS 153567-97-6), molecular formula C13H13NOS2 and molecular weight 263.38 g/mol, is a CATO reference standard with documented purity and traceability.
(5E)-2-Mercapto-5-(mesitylmethylene)-1,3-thiazol-4(5H)-one 153567-97-6 4779AD C13H13NOS2 (C13H13NOS2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (5E)-2-Mercapto-5-(mesitylmethylene)-1,3-thiazol-4(5H)-one 153567-97-6 4779AD C13H13NOS2 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
