Bromophos Chemical Properties,Uses,Production

Description

Bromophos is an obsolete organophosphate insecticide. It ha a moderate aqueous solubility and is quite volatile. It is not generally persistent in soil systems but has the potential to leach to groundwater. It is highly toxic to honeybees and aquatic invertebrates but slightly less so to most other species. Bromophos is moderately toxic to mammals if ingested.

Uses

Bromophos is a pesticide residue that has been found in plants from Southeast Asia.

Definition

ChEBI: Bromofos is an organic thiophosphate.

Production Methods

The commercial production of bromophos, involves synthesising the active compound O,O-dimethyl O-(2,5-dichloro-4-bromophenyl) thiophosphate through a multi-step chemical process. It begins with the preparation of a halogenated phenol, specifically, 2,5-dichloro-4-bromophenol, which is then reacted with dimethyl thiophosphoryl chloride under controlled conditions to form the thiophosphate ester. This reaction typically occurs in the presence of a base, such as pyridine or triethylamine, to neutralize the hydrochloric acid by-product.

Mechanism of action

Broad-spectrum, non-systemic with contact and stomach action. Indirect Acetylcholinesterase (AchE) inhibitor via bromoxon metabolite

Pesticide Type

Insecticide
