| 2,2'-Dimethyl-[1,1'-biphenyl] -4,4'-Diamine Usage And Synthesis |
| Chemical Properties | Pink particles | | Uses | 2,2''-Dimethyl-[1,1''-biphenyl]-4,4''-diamine (cas# 84-67-3) is a useful reagent for manufacturing cured films and semiconductor devices. | | Uses | M-TOLIDINE is used for preparation polyimide and epoxy resin material.
| | Preparation |
M-Tolidine is made by the reduction of m-nitrotoluene with zinc dust and sodium hydroxide solution. The subsequent rearrangement is carried out with hydrochloric acid or sulfuric acid and gives rise to m-tolidine dihydrochloride or m-tolidine sulfate, which are isolated as salts. The free base is diffificult to isolate and is therefore not a commercial product.
| | Chemical Reactivity | M-Tolidine gives no color in the presence of iron(III) chloride. It is tetrazotized with nitrite and acid and couples to form dyes. |
