화학적 성질
m-Tolidine is pink particles and can form prisms when exposed to water. It is soluble in cold water, alcohol, and ether. In the presence of iron(III) chloride, m-Tolidine does not produce any color. It is tetrazotized with nitrite and acid and couples to form dyes.

용도
용도
M-TOLIDINE is used for preparation polyimide and epoxy resin material.
제조 및 합성 방법
제조 방법
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.
