138-36-3 - Introduction

4-bromobenzensulfonic ACID MONOHYDRATE is an organic compound with a chemical formula of C6H5BrO3S and a molecular weight of 249.07g/mol. It has a density of 1.94 g/mL and a melting point of 115-118 degrees Celsius.

4-bromobenzensulfonic ACID MONOHYDRATE is commonly used as an important raw material and reagent in organic synthesis. One of its main uses is as a catalyst, acid catalyst and oxidant. For example, in the synthesis of aromatic compounds, it can be used as a catalyst and peroxidant for phenolic resins. In addition, it can also be used in the synthesis of dyes, drugs and pesticides.

The method of preparing 4-BROMOBENZENESULFONIC ACID MONOHYDRATE can usually be achieved by the reaction of 4-chlorobenzenesulfonic ACID and copper bromide. First, 4-chlorobenzenesulfonic acid is dissolved in an appropriate solvent, and then copper bromide is gradually added. As the reaction proceeds, the reaction system turns orange-yellow. After completion of the reaction, the MONOHYDRATE of 4-bromobenzensulfonic ACID MONOHYDRATE can be obtained by crystallization.

When using and handling 4-bromobenzensulfonic ACID MONOHYDRATE, the following safety precautions should be paid attention to: 1. Avoid contact with skin, eyes and mucous membranes. 2. Use should wear appropriate protective gloves, glasses and protective clothing. Avoid inhaling its vapor and dust, and ensure that the operation is carried out in a well-ventilated place. 4. Wash the contaminated skin or eyes with plenty of water after the operation. 5. Store it in a sealed container, away from fire and oxidant.
