The precise understanding of a chemical compound's properties is fundamental to its successful application in synthesis and research. 2-Chloro-5-cyanophenylboronic acid, identified by CAS number 936249-33-1, is a prime example of a functionalized aromatic boronic acid whose specific chemical attributes make it highly valuable. As a leading 2-chloro-5-cyanophenylboronic acid supplier China, NINGBO INNO PHARMCHEM CO.,LTD. ensures that these critical properties are maintained to the highest standards. Chemically, 2-Chloro-5-cyanophenylboronic acid possesses a molecular formula of C7H5BClNO2 and a molecular weight of approximately 181.38 g/mol. Its structure features a benzene ring substituted with a chlorine atom, a cyano group, and a boronic acid moiety (-B(OH)2). The electron-withdrawing nature of both the chlorine atom and the cyano group influences the reactivity of the boronic acid functional group, making it an excellent nucleophile in various cross-coupling reactions, particularly the Suzuki-Miyaura coupling. This makes it a highly sought-after chemical intermediate for constructing complex organic molecules. Physically, this compound typically appears as a white powder, with a purity often specified at 97% or 98%. Its melting point and boiling point are important parameters for handling and reaction optimization. While specific data may vary slightly depending on the source and purity, these properties are well-documented for chemists looking to buy 2-chloro-5-cyanophenylboronic acid. The stability of boronic acids under appropriate storage conditions (often recommended as cool and dry, away from light) is also a crucial factor for maintaining their efficacy as a fine chemical.
