Product Description

Property

CAS No.: 97-00-7 Formula: C6H3ClN2O4 Molecular Weight: 202.55200

Description

2,4-Dinitrochlorobenzene (DNCB) is an organic compound with the formula (O2N)2C6H3Cl. It is a yellow solid that is soluble in organic solvents. It is an important intermediate for the industrial production of other compounds.
DNCB is produced commercially by the nitration of p-nitrochlorobenzene with a mixture of nitric and sulfuric acids. Other methods afford the compound less efficiently include the chlorination of dinitrobenzene, nitration of o-nitrochlorobenzene and the dinitration of chlorobenzene.
