Uses of 8-Hydroxyquinoline(CAS 148-24-3)

This product is an intermediate of halogenated quinoline anti-amebic drugs, including quiniodoform, chloroiodoquinoline, diioquinoline, etc. These drugs play an anti-amebic role by inhibiting intestinal symbiosis, which is effective for amebic dysentery and has no effect on extraintestinal amebic protozoa. In recent years, it has been reported abroad that this kind of drugs can cause subacute spinal cord optic neuropathy, so this drug has been banned in Japan and the United States. The disease caused by diioquinoline is less common than that caused by chloroiodoquinoline. 8-hydroxyquinoline is also an intermediate of dyes and pesticides. Its sulfate and copper salt are excellent preservatives, disinfectants and fungicides. This product is a complexometric titration indicator for chemical analysis.
