2-Amino-5-fluorobenzoic asidhi CAS 446-08-2 Application

5-Fluoroanthranilic acid yakagadzirwa kubva ku2-methyl-4-fluoronitrobenzene sechinhu chekutanga. Inoshandisa Raney nickel sechinhu chinokonzeresa uye inosangana necatalytic hydrogenation kuderedza ne2-methyl-4-fluoronitrobenzene pa50 °C. Mushure mekusefa kubva kune catalyst mu Chemicalbook, solvent inobviswa ne distillation kuti iwane 5-fluoro-2-aminotoluene. , uyezve oxidized ne potassium permanganate, acidified uye kusefa kuwana crude chigadzirwa, uye kucheneswa nealkali-soluble acid precipitation kuwana pureer yekupedzisira chinangwa chigadzirwa.
