:4-Methylbenzenesulfonyl bromide
Description:
4-Methylbenzenesulfonyl bromide, also known as p-toluenesulfonyl bromide, is an organic compound characterized by the presence of a toluene moiety with a sulfonyl group and a bromine atom. It features a sulfonyl group (-SO2-) attached to a methyl-substituted benzene ring, making it a derivative of toluenesulfonic acid. This compound is typically a white to light yellow solid and is known for its reactivity, particularly in nucleophilic substitution reactions, where it can act as a sulfonylating agent. It is soluble in organic solvents such as dichloromethane and acetone but has limited solubility in water. 4-Methylbenzenesulfonyl bromide is often used in organic synthesis, particularly in the preparation of sulfonamides and other sulfonyl derivatives. Due to its reactivity, it should be handled with care, as it can be corrosive and may cause irritation upon contact with skin or eyes. Proper safety precautions, including the use of personal protective equipment, are essential when working with this compound.
