4,5-Dichloro-1,2-benzenediamine Chemical Properties,Uses,Production
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.]
