| Hazard Information | Back Directory | [Description]
Chloroxynil is an obsolete herbicide that was used to control broadleaved weeds. | [Uses]
Chloroxynil is used as pharmaceutical intermediates. | [Production Methods]
Production information for Chloroxynil is absent in the general literature. However, as a chlorinated analogue of bromoxynil, chloroxynil would have been manufactured by selective chlorination of a hydroxy substituted benzonitrile precursor, typically 4 hydroxybenzonitrile, followed by controlled introduction of chlorine atoms at the 3 and 5 positions of the aromatic ring. The resulting 3,5 dichloro 4 hydroxybenzonitrile would then be purified by crystallisation to yield technical grade chloroxynil. | [Mechanism of action]
Selective, contact action with some systenic activity. Inhibits photosynthesis | [Pesticide Type]
