Mainly used for the manufacture of iodide, also used for the preparation of pesticides, feed additives, dyes, iodine, test paper, medicine and other electronic industry materials, as a high purity reagent. Uses for capacity analysis and colorimetric analysis uses in medicine mainly used as a disinfectant is used to manufacture inorganic iodide and organic iodide basic raw materials, mainly used in medicine and health, used to manufacture various iodine preparations, fungicides, disinfectants, deodorant, analgesic and radioactive substances antidote. It is the raw material of making pesticide, also is the feed additive of livestock. Bacteriostatic agent used industrially in synthetic dyes, smoke extinguishers, photographic emulsions and cutting oil emulsions. Single-crystal prisms for electronic instruments, polarizers for optical instruments, glass that can pass through infrared rays. Used for leather and special soaps. Iodine is a good catalyst for chemicalbookization, isomerization and dehydrogenation of methyl groups in organic synthesis reactions. Also used as alkane and olefin separation agent. Used as a stabilizer for rosin, tall oil and other wood products. Also used as high purity zirconium, titanium, hafnium, silicon and germanium refining agent. Uses Disinfection, sterilization. Mainly used in the manufacture of iodide, used in the manufacture of pesticides, feed additives, dyes, iodine, test paper, medicine, etc., used in the preparation of equivalent solvent, determination of iodine price, calibration of sodium thiosulfate solution concentration, solution can be used as disinfectant. It is used for the calibration of sodium thiosulfate standard solution, determination of iodine value of oil, color reaction of magnesium and acetate, production of iodide and iodide, etc. Colorimetric determination of starch. Serum non - protein nitrogen and amylase were determined. Solid violet and toluidine blue iodine solutions were prepared. The catalyst. Disinfectant.
