7134-41-0 - Introduction

The acid, also known as 4-mercapto benzene sulfonic acid, is an organic compound with a chemical formula of C6H6O3S2. The following is a description of its nature, use, preparation and safety information:

Nature:
acid is a colorless to light yellow crystal or powder, soluble in water and some organic solvents. It is a strong acid that can react with bases to form salts and can form complexes with metals. It is stable in humid air, but easy to oxidize when exposed to strong oxidants and oxygen.

Use:
acid is often used as a catalyst, complexing agent and reducing agent in chemical laboratories, especially in the field of organic synthesis and electrochemistry. It can be used in organic reactions such as oxidation-reduction reaction, decolorization, dehydration, sulfonation reaction and coupling reaction. In addition, it is also used in the dye industry, pharmaceutical industry and electroplating industry.

Method:
sulfuric acid is usually prepared by reacting sulfuric acid with sodium sulfide after chlorination or sulfonation of sulfuric acid. Specific synthetic methods also include reduction of nitrobenzene tin sulfate, Ortho-carboxylation and condensation of p-nitrobenzene sulfonic acid, etc.

Safety Information:
and acid are irritating and corrosive. Contact with the skin and eyes can cause reactions such as burning pain, redness and eye conjunctivitis. Wear appropriate protective measures such as gloves and goggles during use. During storage and use, keep away from open flames and heat sources, and avoid contact with oxidants. If inhaled or ingested by mistake, seek medical attention immediately.
