4,5-Dichloro-1,2-benzenediamine Usage And Synthesis

Chemical Properties

red-brown to brown crystalline powder

Uses

It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff.

Purification Methods

Reflux the amine with activated charcoal in CH2Cl2, followed by recrystallisation from Et2O/pet ether or pet ether [Koolar & Kochi J Org Chem 52 4545 1987]. Alternatively, recrystallise the diamine from hexane, *C6H6, pet ether or H2O (Na2SO4) and sublime it at 150o/15mm. [Beilstein 13 IV 72.]
