Industrial organic synthesis prepared oximes. The pharmaceutical industry made sulfamethoxazole intermediates and synthesis of anticancer drugs (hydroxyurea) sulfa drugs and raw materials. Dye made isatin intermediates. Also used to make soaps of fatty acids and antioxidants. Hydrochloride is an oxime carbamate insecticides such as esters methomyl, aldicarb, methomyl, such as dual-sulfur intermediates, but also the preparation of 2,6 - dichlorobenzene nitrile raw material, such as o-dichlorobenzene oxime . Industry as a reducing agent in organic synthesis, preparation of oximes, also used in the production of pharmaceuticals, dyes for color photography and film photofinishing. Not used in the synthetic rubber industry colored suspension agent in the short term, for the analysis of trace chemical testing aldehydes and ketones and organic acid analysis, the analysis is used to electrically pole agent in medicine for the production of sulfamethoxazole, danazol, ethinyl estradiol, norethindrone, methyl testosterone, hydroxyurea, Librium, etc. This product is used for color photography and film photofinishing. As a reducing agent in organic synthesis industry to prepare oxime and anticancer drugs and sulfa drugs. In medicine is also used to produce sulfamethoxazole, danazol, ethinyl estradiol, norethindrone, methyl testosterone, hydroxyurea, Librium, etc. In the synthetic rubber industry, as a short-term suspension without coloring agents. Analytical chemistry, trace organic compounds for aldehydes and ketones and acid test analysis, power analysis is used to pole agent. Also used in the production of dyes.
