2-Bromo-5-(chlorosulfonyl)benzoic acid(CAS: 3285-31-2)

2-Bromo-5-(chlorosulfonyl)benzoic acid is a crystalline solid with a molecular weight of approximately 310.03 g/mol. Its solubility in water is limited, typically around 0.1 g/L at 25°C. The compound is highly reactive due to the presence of the sulfonyl chloride group, which makes it a potent electrophile in nucleophilic substitution reactions. It is insoluble in most organic solvents except for strong polar aprotic solvents like dimethylformamide.

2-Bromo-5-(chlorosulfonyl)benzoic acid is typically synthesized through the bromination of 5-chlorosulfonylbenzoic acid with bromine in an aqueous solution. The reaction is performed under acidic conditions using concentrated sulfuric acid. The yield is generally high, and the selectivity of the bromination is excellent, due to the inherent reactivity of the sulfonyl chloride group.

2-Bromo-5-(chlorosulfonyl)benzoic acid is utilized in various industries, particularly in pharmaceuticals for the synthesis of certain medicinal compounds, in the polymer industry for the production of functional polymers, and in the electronics industry for the development of sensors and semiconductor materials.

When handling 2-Bromo-5-(chlorosulfonyl)benzoic acid, it is crucial to wear appropriate personal protective equipment (PPE), including gloves, safety goggles, and a lab coat. The compound should be handled in a well-ventilated area or a fume hood to minimize exposure to its fumes. Spills should be handled immediately using a suitable absorbent material, and the area should be cleaned with water and detergent. Always refer to the Material Safety Data Sheet (MSDS) for specific safety guidelines.
