What is Bis(2-nitrophenyl) disulfide?

Chemical properties

yellow to yellow-green crystalline powder

The Uses of Bis(2-nitrophenyl) disulfide

Bis(o-Nitrophenyl) Disulfide, can be used in a PVC membrane electrode as a sensor for zinc ions. It is also a building block used for the synthesis of various pharmaceutical compounds. It can be used for the preparation of a series of 4-Azaindole inhibitors of c-Met kinase.

General Description

PVC membrane electrode based on bis(2-nitrophenyl)disulfide carrier acts as sensor for zinc ions. Bis(2-nitrophenyl) disulphide undergoes mechanochemical grinding with bis(4-chlorophenyl)disulfide in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene catalyst via metathesis reaction to yield non-symmetrical heterodimer 4-chlorophenyl-2′-nitrophenyl disulfide.

Purification Methods

Purify the disulfide by recrystallisation from glacial AcOH or from *C6H6 and the yellow needles are dried in an oven at 100o until the odour of the solvent is absent. It is sparingly soluble in EtOH and Me2CO. [Bogert & Stull Org Synth Coll Vol I 220 1941, Bauer & Cymerman J Chem Soc 3434 1949, Beilstein 6 IV 1672.]
