2,2'-디클로로벤지딘 C화학적 특성, 용도, 생산
화학적 성질
3,3' -Dichlorobenzidine is barely discolored on exposure to air and is chemically resistant to water. Oxidizing agents, such as bromine water, potassium dichromate, and iron(III) chloride, cause the formation of a green color. With gold, the green color is still detectable at a dilution of 1 : 5000000. N-Acetyl-3,3' -dichlorobenzidine and N,N' - diacetyl-3,3' -dichlorobenzidine form when 3,3' - dichlorobenzidine is treated with acetic anhydride in dilute alcohol. The tetrazotizing behavior is similar to that of benzidine and o-tolidine.
용도
4,4''-Diamino-2,2''-Dichlorobiphenyl is a useful reactant for the synthesis of benzidine, L-?proline, and diaminofluorene derivatives which are hepatitis C virus NS5A inhibitors.
Solubility in water
It is almost insoluble in water but readily soluble in alcohol.
Purification Methods
Crystallise the benzidine from EtOH or H2O. [Beilstein 13 H 234, 13 I 66, 13 II 106, 13 III 477, 13 IV 384.]
