2-(2-Fluorophenoxy)-N-(2-(6-oxo-3-phenylpyridazin-1(6H)-yl)ethyl)propanamide (CAS 1049220-44-1), molecular formula C21H20FN3O3 and molecular weight 381.40 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Fluorophenoxy)-N-(2-(6-oxo-3-phenylpyridazin-1(6H)-yl)ethyl)propanamide (C21H20FN3O3) contains a steroid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
