Description
Compared with other compounds in its class, the molecular weight of 466.55 g/mol gives 2-Amino-5-benzylidenethiazol-4(5H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Amino-5-benzylidenethiazol-4(5H)-one (CAS 14230-00-3), molecular formula C19H24N4O2C2H6O4S and molecular weight 466.55 g/mol, is a CATO reference standard with documented purity and traceability.
2-Amino-5-benzylidenethiazol-4(5H)-one (C19H24N4O2C2H6O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
