Specification:

?8-Hydroxyquinoline (CAS NO.148-24-3) is a white to off-white or faintly yellow crystalline powder with phenolic odor.It is?insoluble in water. 8-Hydroxyquinoline darkens on exposure to light and readily forms stable metal chelates. It is incompatible with strong oxidizers and it is also incompatible with many metal ions.
It? is a monoprotic bidentate chelating agent. Related ligands are the Schiff bases derived from salicylaldehyde, such as salicylaldoxime and salen. In neutral solution, the hydroxyl is in the protonated form (pKa=9.89) and the nitrogen is not protonated (pKa=5.13).However, an excited-state zwitterionic isomer exists in which H+ is transfered from the oxygen (giving an oxygen anion) to the nitrogen (giving a protonated nitrogen cation).
