Halogenated aromatics are organic compounds that contain one or more halogen atoms, such as fluorine, chlorine, bromine, or iodine, attached to an aromatic ring. These compounds are derived from aromatic hydrocarbons, which are characterized by their stable ring structure and delocalized electrons. Halogenation can alter the chemical properties of the original aromatic compound, making them useful in various applications. These compounds are commonly found in industrial processes, pharmaceuticals, and agrochemicals. However, some halogenated aromatics can be toxic or persistent in the environment, raising concerns about their impact on human health and ecosystems. Proper management and regulation are essential to mitigate these risks.
