2-[(4-Fluorophenyl)methyl]-4-(5-methyl-1,2,4-oxadiazol-3-yl)-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepine-1,3-dione (CAS 1775439-08-1) is a high-purity analytical reference standard with the molecular formula C19H19FN4O3 and a molecular weight of 370.38 g/mol.
2-[(4-Fluorophenyl)methyl]-4-(5-methyl-1,2,4-oxadiazol-3-yl)-1H,2H,3H,5H,6H,7H,8H,9H-pyrimido[1,6-a]azepine-1,3-dione (C19H19FN4O3) 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.
