8-hydroxyquinoline 183815-54-5

Storage method 8-Hydroxyquinoline is easily oxidized, so it should be sealed and protected from light when stored. It should generally be placed in a vacuum desiccant. It should also be inspected before use to see if it has deteriorated to avoid affecting the experimental results. It is generally prepared and used immediately. Chemical properties White needle-shaped crystals. Melting point 76℃, boiling point 266.6℃ (100.3kPa). It is easily soluble in ethanol, benzene, chloroform, acetone and dilute acid, and insoluble in water. Uses It is used as a reagent for the determination of bismuth, magnesium, copper, zinc and organic element nitrogen; it is used as a pharmaceutical intermediate, and is the raw material for the synthesis of chlorquinolone, iodoquinol and chloranthamine, and is also a dye, pesticide intermediate, and extractant. Uses: Pharmaceutical intermediates; pesticide and dye intermediates. Uses: Precipitants and extractants for precipitation and separation of metal ions. It can complex with the following metal ions: Cu+2, Be+2, Mg+2, Ca+2, Sr+2, Ba+2, Zn+2, Cd+Chemicalbook2, 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. Uses: 8-Hydroxyquinoline is an intermediate for halogenated quinoline anti-amoebic drugs, including quiniodoform, chloroiodoquinoline, diiodoquinoline, etc. This type of drug exerts its anti-amoebic effect by inhibiting intestinal symbiotic bacteria, is effective against amoebic dysentery, and has no effect on extraintestinal amoeba. In recent years, foreign reports have shown that this type of drug can cause subacute spinal optic neuropathy, so the drug has been banned in Japan and the United States. Iodoquinol is less common than chloroiodoquinol in causing this disease. 8-Hydroxyquinoline is also an intermediate for dyes and pesticides. Its sulfate and copper salt are excellent preservatives, disinfectants and mildew inhibitors. This product is a complexometric titration indicator for chemical analysis.
