Chlorfenvinphos is the common name of an organophosphorus compound that was widely used as an insecticide and an acaricide. The molecule itself can be described as an enol ester derived from dichloroacetophenone and diethylphosphonic acid. Chlorfenvinphos has been included in many products since its first use in 1963. However, because of its toxic effect as a cholinesterase inhibitor it has been banned in several countries, including the United States and the European Union. Its use in the United States was cancelled in 1991. The pure chemical is a colorless solid, but for commercial purposes, it is often marketed as an amber liquid. The insecticides, mostly used in liquid form, contain between 50% and 90% chlorfenvinphos. The substance easily mixes with acetone, ethanol, and propylene glycol. Furthermore, chlorfenvinphos is corrosive to metal and hydrolyzes in the environment. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

3-bromophenylacetic acid belongs to the derivatives of phenylacetic acid and is used in the pharmaceutical industry for the production of drugs such as penicillin and dibazol. It is also a key synthon in the preparation of pesticides and plant growth hormones.

It is a sensitive reagent for the determination of zirconium and can separate zirconium from titanium, iron, aluminum, copper and other metals.

2-aminobenzonitrile compounds are useful chemical and pharmaceutical intermediates, which are widely used in the synthesis of dyes, pesticides and pharmaceuticals. For example, tacrine for the treatment of senile dementia can be obtained by reacting 2-aminobenzonitrile with cyclohexanone; Vinacline, a tacrine derivative, was synthesized by condensation of 2-aminobenzonitrile with 1,3-cyclohexanedione; It is used to synthesize potential anti malarial reagents.

Sodium difluorochloroacetate can be used as organic synthesis reagent, pesticide and pharmaceutical intermediate. For example, it can be used in the synthesis of intermediate of roflumilast.
