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.
2-(1-Butyl-2-oxoindolin-3-ylidene)-6-phenyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione (CAS 607385-06-8) is a high-purity analytical reference standard with the molecular formula C23H18N4O3S and a molecular weight of 430.48 g/mol.
The molecular framework of 2-(1-Butyl-2-oxoindolin-3-ylidene)-6-phenyl-2H-thiazolo[3,2-b][1,2,4]triazine-3,7-dione (C23H18N4O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
