4-Bromochlorobenzene, bearing the CAS number 106-39-8, stands as a cornerstone intermediate in modern organic chemistry. Its distinct molecular structure and reactivity make it an invaluable component for synthesizing a vast array of compounds, from life-saving pharmaceuticals to advanced materials. As a premier manufacturer and supplier of specialty chemicals, we delve into the chemical essence, synthesis pathways, and critical applications that define this important aromatic halide.

Chemical Profile and Properties

Characterized by its designation as an aromatic halide, 4-Bromochlorobenzene is a halogenated benzene derivative. Its physical state is typically described as a colorless needle or flaky crystal, with a melting point generally falling between 64-67°C and a boiling point around 196°C. The density is reported at 1.651, and its flash point is 196°C. A key attribute for its utility is its high purity, often available at ≥98.5% via Gas Chromatography (GC). This compound is soluble in many organic solvents like ether, benzene, and chloroform, but sparingly soluble in water. Its chemical inertness under standard conditions, coupled with the reactivity of its halogen substituents under specific reaction conditions, makes it a highly desirable intermediate.

Synthesis of 4-Bromochlorobenzene

The synthesis of 4-Bromochlorobenzene typically involves electrophilic aromatic substitution reactions on chlorobenzene or bromobenzene. A common industrial route might involve the direct bromination of chlorobenzene, often using a brominating agent like elemental bromine in the presence of a Lewis acid catalyst, such as iron(III) bromide or aluminum chloride. This reaction preferentially directs the bromine atom to the para position relative to the chlorine atom due to the activating and ortho, para-directing nature of the chlorine substituent.
