These reactions can be monitored by element analysis and are used in the study of carcinogenesis. The compound has been shown to have toxic effects on tissues and animals, but these effects are not well understood at this time. Techniques such as FTIR spectroscopy and animal studies have been used to determine some of the functional groups present in 2-butylthiophene.

2-Aminothiophen-3-yl)(4-bromophenyl)methanone is a new compound that is being developed as a potential antiviral agent. Covid-19, the trade name for 2-aminothiophen-3-yl)(4-bromophenyl)methanone, prevents the replication of viruses by binding to their nucleic acids and blocking their ability to produce proteins. Covid-19 has been shown to be effective against both influenza A and B viruses in cellular and animal models. The antiviral activity of Covid-19 is due to its ability to bind to viral nucleic acid, preventing the production of proteins vital for viral replication. This compound has also been shown to have anti-inflammatory properties, which may be due to its ability to inhibit the production of amyloid plaques in mice with Alzheimer's disease.
