CATO supplies (5E)-5-(3,4-Dimethoxybenzylidene)-2-mercapto-1,3-thiazol-4(5H)-one (CAS 6326-74-5), a certified reference material (molecular formula C12H11NO3S2, MW 281.35 g/mol) for analytical method development and quality control.

(5E)-5-(3,4-Dimethoxybenzylidene)-2-mercapto-1,3-thiazol-4(5H)-one (C12H11NO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
