In the realm of fine chemical synthesis, a thorough understanding of the properties of intermediates is paramount for successful and efficient reactions. 2-Bromo-4-chlorobenzaldehyde, identified by CAS number 84459-33-6, is a compound that offers a unique combination of chemical reactivity and physical characteristics, making it highly sought after by researchers and manufacturers. This article delves into the key properties of this versatile intermediate, highlighting why it is a cornerstone in many advanced chemical processes.

Chemically, 2-Bromo-4-chlorobenzaldehyde is a substituted benzaldehyde, featuring a bromine atom at the ortho position and a chlorine atom at the para position relative to the aldehyde group. This arrangement of electron-withdrawing halogens significantly influences the reactivity of the aldehyde functionality and the aromatic ring. The aldehyde group itself is susceptible to various reactions, including oxidation, reduction, and nucleophilic addition. Meanwhile, the halogen substituents provide sites for nucleophilic aromatic substitution or participation in transition-metal-catalyzed cross-coupling reactions. These properties make it an excellent building block for constructing complex organic molecules.

Physically, 2-Bromo-4-chlorobenzaldehyde is typically presented as a white to light yellow crystalline solid. Its melting point, often cited around 71°C, indicates its solid state under standard laboratory conditions and provides a useful parameter for purity assessment. The molecular formula C7H4BrClO, with a molecular weight of approximately 219.47 g/mol, is critical information for stoichiometric calculations in synthesis. While precise boiling point data can vary depending on pressure, values around 264.6 °C at 760 mmHg are reported, suggesting its stability at elevated temperatures relevant to certain reactions. A purity level of ≥97.0% is commonly specified, ensuring minimal interference from impurities in sensitive synthetic steps.
