2-Bromobenzaldehyde, identified by its CAS number 6630-33-7, is a valuable organic compound characterized by its light yellow liquid appearance. This aromatic aldehyde is a cornerstone in many organic synthesis pathways, prized for its dual reactivity stemming from both the aldehyde group and the ortho-positioned bromine atom. Understanding its properties is key for chemists and procurement professionals looking to leverage its potential.

Chemically, 2-Bromobenzaldehyde possesses the molecular formula C7H5BrO, with a molecular weight of approximately 185.02 g/mol. Its physical properties include a melting point typically around 16-19°C and a boiling point of 230°C. This makes it a liquid at standard room temperature, simplifying handling in many laboratory and industrial settings. Its solubility profile indicates it is soluble in common organic solvents like alcohol and benzene but insoluble in water, a typical characteristic for brominated aromatic compounds.

The primary utility of 2-Bromobenzaldehyde lies in its extensive use in organic synthesis. It acts as a versatile building block for creating more complex molecules. For instance, it is employed in enantio- and diastereoselective aldol reactions, which are critical for constructing chiral centers in organic molecules. Furthermore, it serves as a precursor for various substituted benzaldehydes and benzoic acids, as well as in the preparation of heterocyclic compounds and complex aromatic structures through reactions involving the bromine substituent.

For businesses and researchers aiming to purchase 2-Bromobenzaldehyde, it's important to identify reliable sources. Many manufacturers and suppliers offer this chemical, with a significant number based in China, known for their competitive pricing and large-scale production capabilities. When you buy 2-Bromobenzaldehyde, prioritize suppliers who can provide detailed product specifications, purity analysis (e.g., >97% or >99% assay), and a clear indication of their manufacturing or distribution capabilities. Exploring options from established chemical distributors ensures you receive a quality product for your synthesis needs.

In conclusion, 2-Bromobenzaldehyde is a fundamental chemical intermediate with a wide range of applications in organic synthesis. Familiarity with its properties and knowing where to source it from reputable manufacturers and suppliers is crucial for successful laboratory and industrial operations.
