<p>3,6-Bis([1,1'-biphenyl]-4-yl)-2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione is an analytical reagent that has been used as a corrosion inhibitor in coatings. It has been shown to promote the formation of reactive oxygen species and inhibit the growth of bacteria by binding to DNA. The biphenyl group is known for its ability to form intermolecular hydrogen bonding with chloride ions and aliphatic hydrocarbons. This reaction yields a biphenyl aryl halide intermediate that reacts with an acid catalyst to produce a reactive oxygen species (ROS) and convert chloride ions into chloride radicals. The ROS can then react with other molecules such as particles to form free radicals that are highly corrosive. The average particle diameter for this product is in the range of 10 nm - 100 nm.</p>

<p>2-Amino-6-chloropyrimidin-4(3H)-one (ACPP) is a betaine that has been shown to exhibit potent activity against clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA). It is a mesomeric molecule, which means that it can exist as two different tautomers. The frequency of the absorption bands in the FTIR spectra for ACPP are characteristic of the carbenes and ethanolamine tautomers. The presence of these tautomers may be due to stabilization from the nucleophilic character of the nitrogen atom in betaines. Betaines are also able to form polymersized chains by reacting with themselves or other molecules, such as ethanolamine.</p>
