Phenyl-bistrifluormethyl-dibrom-phosphoran, also known as bromophos, is a phosphorus-containing organophosphorus compound with the chemical formula C6H3Br2F6P. It is a colorless to pale yellow liquid with a pungent odor and is used as an insecticide and acaricide in agriculture. Bromophos is effective against a wide range of pests, including aphids, mites, and caterpillars, and is known for its contact and stomach action. However, due to its potential health risks and environmental concerns, its use has been restricted or banned in several countries. It is important to handle bromophos with care, as it can be toxic to humans and animals, and can cause harm to the environment if not managed properly.
