Applicazioni

2-Amino-5-nitrophenol has been used as starting material in the synthesis of series of (Z)-2-(substituted aryl)-N-(3-oxo-4-(substituted carbamothioyl)-3,4-dihydro-2H-benzo[b][1,4]oxazin-7-yl) hydrazine carboxamides, as semi permanent (nonoxidative) hair colorant and as toner in permanent (oxidative) hair dye products, in synthesis of series of 7-benzylamino-2H-1,4-benzoxazin-3(4H)-ones, anticonvulsant agents. Also used as a reactant for, diazotation and coupling reactions, preparation of biologically and pharmacologically active molecules. It is also applied in hair dyes and to make azo dyes.

Note

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
