2-Bromo-1H-imidazole is an environmental pollutant that has been detected in the atmosphere, water, and soil. It is used as a pesticide and has been found to be an impurity in biphenyl. 2-Bromo-1H-imidazole can be used as a substrate for the Suzuki coupling reaction or as a starting material for the synthesis of imidazole derivatives. The compound spontaneously fragments under acidic conditions to form nitric acid and hydrogen bromide. 2-Bromo-1H-imidazole has been shown to inhibit hepatitis C virus (HCV) replication and induce cancer cell apoptosis in vitro.
2-Bromo-1H-imidazole is also known to cause DNA fragmentation in cells through oxidation by reactive oxygen species or through spontaneous decomposition of the molecule into acid, bromine radicals, and ammonia.

2-Thiophenemethanol is a colorless liquid that has a strong, disagreeable odor and is soluble in water. It can be prepared by the reaction of 2-methylpropanal with trifluoroacetic acid. This compound reacts with methapyrilene to form polymers, which have a cationic character. The chemical structure of the molecule was determined by a combination of experimental techniques such as proton nuclear magnetic resonance spectroscopy, infrared spectroscopy, and mass spectrometry. Hydrogen bonding plays an important role in the structure of 2-thiophenemethanol as it forms intermolecular hydrogen bonds with neighboring molecules. The chemical formula for this compound is CH3C6H4SO2H. Hydrochloric acid can be used to break down this compound into methylmercaptan and sulfur dioxide.
