3-(4-((3-Fluorophenyl)sulfonyl)piperazin-1-yl)-6-(3-methyl-1H-pyrazol-1-yl)pyridazine (C18H19FN6O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
3-(4-((3-Fluorophenyl)sulfonyl)piperazin-1-yl)-6-(3-methyl-1H-pyrazol-1-yl)pyridazine (CAS 1013756-89-2), molecular formula C18H19FN6O2S and molecular weight 402.45 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.
