2-Bromochlorobenzene (CAS 694-80-4) is a bifunctional aromatic compound that holds significant value in the field of synthetic chemistry. Its molecular structure, C6H4BrCl, with a molecular weight of 191.45 g/mol, features both a bromine and a chlorine atom positioned ortho to each other on a benzene ring. This arrangement dictates its reactivity and makes it a versatile substrate for a variety of chemical transformations. Understanding its physical and chemical properties is fundamental for chemists aiming to utilize it effectively in their research and development projects.

Physically, 2-Bromochlorobenzene is described as a clear, colorless to yellow-orange liquid. Its notable properties include a melting point between -13 to -11°C and a boiling point of approximately 204°C at atmospheric pressure. The density is around 1.638 g/mL at 25°C, and it exhibits a refractive index of n20/D 1.582. Its solubility in water is low, reported at 0.045 g/L at 25°C, but it is soluble in common organic solvents. These characteristics are important for selecting appropriate reaction conditions, solvents, and purification methods.

Chemically, the presence of both halogen atoms on the benzene ring provides distinct reaction pathways. The bromine atom is generally more reactive than the chlorine atom in many substitution reactions, allowing for selective functionalization. This differential reactivity is often exploited in complex syntheses. For instance, palladium-catalyzed cross-coupling reactions, such as Suzuki or Sonogashira couplings, can be selectively performed at the carbon-bromine bond, introducing new carbon-carbon bonds and building molecular complexity. Subsequent reactions can then target the carbon-chlorine bond or other positions on the aromatic ring.

The utility of 2-Bromochlorobenzene as an intermediate is particularly evident in the synthesis of pharmaceuticals and agrochemicals. It serves as a key building block for creating more complex molecular scaffolds that form the basis of many active ingredients. Researchers looking to 'buy 2-bromochlorobenzene' for organic synthesis often seek high purity grades to ensure efficient reactions and high yields. Purchasing from a reliable 'chemical manufacturer' that specifies purity levels (e.g., ≥99%) and provides comprehensive product data is crucial for experimental success.

Furthermore, 2-Bromochlorobenzene is recognized for its application in analytical chemistry. It can be used as a reference standard in techniques like Gas Chromatography-Mass Spectrometry (GC-MS) or High-Performance Liquid Chromatography (HPLC) for identifying and quantifying related compounds or impurities. This analytical role reinforces its importance throughout the research and development lifecycle.

For scientists and procurement professionals aiming to 'purchase 2-bromochlorobenzene', understanding its chemical properties and application scope is paramount. Sourcing this intermediate from trusted 'suppliers' who emphasize quality, consistency, and reliable delivery, often from regions like China, ensures that synthetic chemistry endeavors can proceed without interruption.
