Methyl (E)-5-((4-chlorophenyl)thio)-4-((((2,4-dichlorobenzyl)oxy)imino)methyl)-1-phenyl-1H-pyrazole-3-carboxylate CAS 400077-38-5

Description

Methyl (E)-5-((4-chlorophenyl)thio)-4-((((2,4-dichlorobenzyl)oxy)imino)methyl)-1-phenyl-1H-pyrazole-3-carboxylate (C25H18Cl3N3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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).

Methyl (E)-5-((4-chlorophenyl)thio)-4-((((2,4-dichlorobenzyl)oxy)imino)methyl)-1-phenyl-1H-pyrazole-3-carboxylate (CAS 400077-38-5) is a high-purity analytical reference standard with the molecular formula C25H18Cl3N3O3S and a molecular weight of 546.85 g/mol.
