The occurrence of 5-(((6-(4-Bromophenyl)pyridazin-3-yl)thio)methyl)-3-(p-tolyl)-1,2,4-oxadiazole is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(((6-(4-Bromophenyl)pyridazin-3-yl)thio)methyl)-3-(p-tolyl)-1,2,4-oxadiazole (CAS 1115285-50-1), molecular formula C20H15BrN4OS and molecular weight 439.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(((6-(4-Bromophenyl)pyridazin-3-yl)thio)methyl)-3-(p-tolyl)-1,2,4-oxadiazole (C20H15BrN4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. 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 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.
