1,4-Dibromo-2-(chloromethyl)benzene is a synthetic compound that has been used as an anti-hepatitis C virus (HCV) agent. It is effective against HCV genotype 1 and 2, but not 3. It has been shown to be active in inhibiting the replication of HCV RNA by binding to the viral enzyme RNA polymerase. This drug has also been found to inhibit the growth of Mycobacterium tuberculosis and is being investigated for use in treating tuberculosis. The drug is prepared by reacting bromobenzene with sodium hydroxide and chloromethyl chloride in aqueous solution at 0°C. Dibromoethane reacts with paraformaldehyde and cuprous cyanide to form 1,4-dibromo-2-(chloromethyl)benzene, which can then be treated with hydrochloric acid to form the desired product.

2-(5-Bromothiophen-2-yl)acetonitrile is an acceptor in organic solar cells and devices. It has a molecular weight of 122.1 g/mol and a melting point of -34 °C, with a solubility of 0.0013g/mL in water. The UV absorption spectrum shows that it absorbs at wavelengths between 270-300 nm. 2-(5-Bromothiophen-2-yl)acetonitrile can be used as an electron donor for semiconducting heterojunction photovoltaic devices and has been shown to have good transport properties. This molecule also has molecular orbitals that are lower than those found in the ground state, which may be due to the presence of hydrogen bonding groups on the phenyl rings or the presence of electron donating groups such as nitro (-NO2) or cyano (-CN).

5-Iodopentanenitrile is a reactive chemical that can be used to produce organic compounds. This compound is an intermediate in the production of 5-iodo-1,3-dihydrobenzofuran and 5-iodoquinoline. It is also used for the production of pharmaceutical intermediates such as fluoroquinolones and alkylating agents. The mechanism of this chemical's reactivity has been studied extensively, which led to the discovery that it reacts by nucleophilic addition at electron deficient carbonyls groups. These reactions are known as Grignard reactions or halolactonizations. This chemical has also been shown to be reactive with biomolecules, such as DNA and RNA, and can bind to their sugar residues.
