Fluorinated aromatic compounds represent a sophisticated class of organic molecules, prized for their unique chemical and physical properties, which stem from the high electronegativity and small atomic radius of fluorine. These characteristics impart enhanced thermal stability, altered electronic properties, and increased lipophilicity to molecules. Among these valuable compounds, 2-Bromo-4-chloro-1-fluorobenzene (CAS 1996-30-1) stands out as a versatile intermediate with growing applications beyond its traditional roles in pharmaceuticals and agrochemicals, extending into advanced materials and specialty chemicals.

Understanding the Molecular Structure and Properties

2-Bromo-4-chloro-1-fluorobenzene, with its molecular formula C6H3BrClF, features a benzene ring substituted with bromine, chlorine, and fluorine atoms. This specific pattern of halogenation is key to its reactivity and the properties it confers upon larger molecules. Typically appearing as a colorless to light yellow liquid, it possesses a boiling point of 180°C and a density of 1.719. These physical attributes are important for chemists working with the compound in synthesis. The presence of multiple halogens provides multiple sites for selective functionalization, making it a valuable building block for creating highly tailored chemical structures.
