What is the effect of 8-hydroxyquinoline?
1. Widely used for the determination and separation of metals. A precipitant and extractant for precipitating and separating metal ions, capable of complexing 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. The standard for organic trace analysis to determine heterocyclic nitrogen, organic synthesis. It is also an intermediate of dyes, pesticides, and haloquinoline based anti amoebic drugs.
2.Used as a pharmaceutical intermediate, it is a raw material for synthesizing clenbuterol, chloroiodoquinoline, and paracetamol, as well as a dye and pesticide intermediate. This product is an intermediate of halogenated quinoline based anti amoebic drugs, including quiniodoform, chloroiodoquinoline, diiodoquinoline, etc. These drugs exert an anti amoebic effect by inhibiting gut symbiotic bacteria, which is effective against amoebic dysentery and has no effect on extracellular amoebic protozoa. According to foreign reports, this type of drug can cause subacute spinal optic neuropathy, so it has been banned in Japan and the United States. Diiodoquinoline is less common in causing this disease than chloroiodoquinoline. 8-hydroxyquinoline is also an intermediate in dyes and pesticides.
3.Adding epoxy resin adhesive can improve the bonding strength and heat aging resistance to metals (especially stainless steel), with a general dosage of 0.5-3 parts. It can be used as a mold inhibitor, industrial preservative, and stabilizer for polyester resin, phenolic resin, and hydrogen peroxide.
4.This product is an intermediate of halogenated quinoline based amoebic drugs, including quinoline iodide, chloroiodoquinoline, diiodoquinoline, etc. It is also an intermediate of dyes and pesticides. Its sulfates and copper salts are excellent preservatives, disinfectants, and mold inhibitors. The maximum allowable content (mass fraction) in cosmetics is 0.3%. Sunscreen products and products for children under 3 years old (such as talcum powder) are prohibited, and the product label should indicate "prohibited for children under 3 years old". When treating bacterial infected skin and bacterial infectious eczema, the mass fraction of 8-hydroxyquinoline in lotion is 0.001%~0.02%. It is also used as a disinfectant, preservative, and fungicide, with strong anti fungal effects. The content (mass fraction) of 8-hydroxyquinoline potassium sulfate used in skin care cream and lotion is 0.05%~0.5%.
