Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-(4-((4-Bromophenyl)sulfonyl)piperazin-1-yl)-6-phenylpyridazin-3(2H)-one.
5-(4-((4-Bromophenyl)sulfonyl)piperazin-1-yl)-6-phenylpyridazin-3(2H)-one (CAS 477872-21-2) is a high-purity analytical reference standard with the molecular formula C20H19BrN4O3S and a molecular weight of 475.36 g/mol.
5-(4-((4-Bromophenyl)sulfonyl)piperazin-1-yl)-6-phenylpyridazin-3(2H)-one (C20H19BrN4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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).
