FAQ

What is Sodium benzenesulfonate (CAS: 515-42-4)?

Sodium benzenesulfonate is an inorganic sodium salt of benzenesulfonic acid, with the chemical formula C6H5NaO3S. It is a white crystalline solid that is soluble in water and commonly used in various industrial applications. The compound has a molecular weight of 184.17 g/mol and is known for its mild corrosive properties when in contact with skin or eyes.

What are the main uses of Sodium benzenesulfonate (CAS: 515-42-4)?

Sodium benzenesulfonate is widely used in the pharmaceutical industry as a sulfonating agent and in the production of detergents and dyes. It also serves as a precursor for other organic compounds and is applied in food processing as a stabilizer. Additionally, it finds use in research for chemical synthesis and in the textile industry for dye fixation and processing.

Is Sodium benzenesulfonate (CAS: 515-42-4) safe?

Sodium benzenesulfonate is considered safe when handled properly. However, it may cause mild irritation to the skin and eyes due to its corrosive nature. It is important to follow safety protocols such as wearing gloves, goggles, and a lab coat. The compound is generally recognized as safe (GRAS) in food applications, but proper ventilation and handling are recommended to ensure safety in industrial settings.

How should Sodium benzenesulfonate (CAS: 515-42-4) be stored?

Sodium benzenesulfonate should be stored in a cool, dry place away from moisture and direct sunlight. It is best kept in a sealed container made of glass or high-density polyethylene (HDPE) to prevent contamination. The storage temperature should be maintained below 25°C, and the compound should be protected from exposure to air to ensure stability and prolong shelf life.
