2-Naphthalenesulfonic acid

Description:

2-Naphthalenesulfonic acid is an aromatic sulfonic acid characterized by its naphthalene ring structure with a sulfonic acid (-SO3H) group attached to the second carbon of the naphthalene. This compound is a white to light yellow crystalline solid that is soluble in water and organic solvents, making it useful in various applications. It has a high melting point and exhibits strong acidity due to the presence of the sulfonic acid group. 2-Naphthalenesulfonic acid is primarily used as a dye intermediate, in the synthesis of surfactants, and as a dispersing agent in various industrial processes. Additionally, it can act as a reagent in organic synthesis and is involved in the production of other chemical compounds. Its derivatives are also significant in the field of pharmaceuticals and agrochemicals. Safety data indicates that it should be handled with care, as it can cause irritation to the skin and eyes. Proper safety measures should be taken when working with this compound in laboratory or industrial settings.

CAS: 120-18-3

2-Naphthalenesulfonic acid is an activated sodium salt that is used to treat wastewater. It has been shown to react with malonic acid, a major component of wastewater, by forming a kinetic and thermodynamic acid complex. The reaction solution then reacts with epidermal growth factor to form benzalkonium chloride. 2-Naphthalenesulfonic acid has been shown to be effective in the treatment of wastewater due to its ability to remove organic materials and inhibit the growth of bacteria.
