English description（英文原文，共 1505 字符）
Product Name:Methyl 5-bromo-2-chlorobenzoate
English Name:Methyl 5-bromo-2-chlorobenzoate
CAS No.:251085-87-7
Aliases:5-Bromo-2-chlorobenzoic acid methyl ester, Methyl 2-chloro-5-bromobenzoate
Molecular Formula:C8H6BrClO2
Physical Properties:This product is a pale yellow to colorless transparent liquid or low-melting solid with a characteristic ester odor. It has a molecular weight of 249.49, a density of approximately 1.6 g/cm³, a boiling point of about 282°C (760 mmHg), and a flash point above 110°C. It is insoluble in water and readily soluble in organic solvents such as methanol, ethanol, dichloromethane, and ethyl acetate. It is stable under normal temperature and pressure but should be protected from strong oxidizing agents and strong bases.
Uses:This product is an important pharmaceutical and agrochemical synthetic intermediate, mainly used in the construction of active molecules containing bromine- and chlorine-substituted aromatic ring structures. As a benzoate ester derivative, it is commonly employed as a substrate in palladium-catalyzed coupling reactions (e.g., Suzuki coupling, Buchwald-Hartwig amination) for the synthesis of biaryl fine chemicals, liquid crystal materials, and pharmaceutical molecular frameworks.
