Chemical Structure
Description
21302-43-2 5-Amino-8-hydroxyquinoline dihydrochloride 5-Amino-8-quinolinol dihydrochloride 5-aminoquinolin-8-ol dihydrochloride (C9H18N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
