  Hot Sale 8-Hydroxyquinoline Fast Delivery 148-24-3 in china

This product is an intermediate of halogenated quinoline anti-amoebic drugs, including quinodoform, chloroiodoquinoline, diiodoquinoline, etc. These drugs play an anti-amoebic effect by inhibiting intestinal symbiotic bacteria, are effective for amoebic dysentery, and have no effect on intestinal amoeba protozoa. In recent years, it has been reported abroad that this class of drugs can cause subacute spinal optic neuropathy, so this drug has been banned in Japan and the United States. Diiodoquinoline is less common than chloroiodoquinoline. 8-Hydroxyquinoline is also an intermediate of dyes and pesticides. Its sulfate and copper salts are excellent preservatives, disinfectants and antifungal agents. This product is a complexometric titration indicator for chemical analysis.
Used as a reagent for the determination of bismuth, magnesium, copper, zinc and organic element nitrogen; used as a pharmaceutical intermediate, it is a raw material for the synthesis of Kexilining, chloroiodoquinoline, and wheezing sensitivity. It is also a dye and pesticide Intermediate, extractant.
Pharmaceutical intermediates; Pesticide and dye intermediates
The precipitant and extractant for precipitating and separating metal ions can be complexed with the following metal ions: cu 2, Be 2, Mg 2, Ca 2, Sr 2, Ba 2, Zn 2, Cd 2, Al 3, Ga 3, In 3, Tl 3, Yt 3, La 3, Pb 2, B 3, Sb 3, Cr 3, MoO 22, Mn 2, Fe 3, Co 2, Ni 2, Pd 2, Ce 3.
used in manufacturing dyes, pesticides and pharmaceutical intermediates; used as complexing indicators and chromatography reagents; also can be used as RNA synthesis inhibitors, and have bactericidal inhibitory effects on Trichoderma vulgaris (Trichophyton mentagrophytes), Myrothecium verrucaria) and Trichoderma viride (Trichoderma viride)

Made from o-aminophenol by cyclize reaction. Glycerol is added into the acid-resistant reaction pot, concentrated sulfuric acid is slowly added under stirring, o-aminophenol and o-nitrophenol are added in sequence, and 65% of the total amount of fuming sulfuric acid is added first. Heating to 125 ℃, stop heating, naturally raise to 140 ℃, and wait for the temperature to drop back to 136 ℃. Continue to add the remaining fuming sulfuric acid and keep the temperature at 137 ℃. After adding acid, keep the temperature for 4 hours, cool to below 100 ℃, draw into an acid-resistant pot containing 10 times the amount of water (calculated by o-aminophenol), stir, heat to 75-80 ℃, and neutralize with 30% sodium hydroxide solution to a pH of 7-7.2. Release the precipitate while it is hot, cool it into a block, and sublimate under reduced pressure to obtain a finished product of 8-hydroxyquinoline.
