Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)-N-(furan-2-ylmethyl)propanamide.
2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)-N-(furan-2-ylmethyl)propanamide (CAS 1203136-03-1), molecular formula C18H16FN3O3 and molecular weight 341.34 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-(4-Fluorophenyl)-6-oxopyridazin-1(6H)-yl)-N-(furan-2-ylmethyl)propanamide (C18H16FN3O3) 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.
