Chemical Structure
Description
6-[(5-{[(4-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one (C26H29N5O2S) contains a steroid 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 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).
6-[(5-{[(4-tert-butylphenyl)methyl]sulfanyl}-4-ethyl-4H-1,2,4-triazol-3-yl)methoxy]-2-phenyl-2,3-dihydropyridazin-3-one (CAS 692738-18-4), molecular formula C26H29N5O2S and molecular weight 475.61 g/mol, is a CATO reference standard with documented purity and traceability.
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.
