Benzenesulfonic acid, 2,5-dimethyl-, sodium salt (1:1)

Description:
Benzenesulfonic acid, 2,5-dimethyl-, sodium salt (1:1), with CAS number 827-19-0, is an organic compound characterized by its sulfonic acid functional group attached to a benzene ring that also features two methyl groups at the 2 and 5 positions. This compound is typically a white to off-white solid and is soluble in water due to the presence of the sodium salt, which enhances its ionic character. It exhibits properties typical of sulfonic acids, such as being a strong acid in aqueous solutions, and can act as a surfactant or detergent due to its amphiphilic nature. The presence of the methyl groups contributes to its hydrophobic characteristics while the sulfonate group provides hydrophilicity. This compound is often used in various applications, including as a reagent in organic synthesis, in the formulation of dyes, and as an additive in industrial processes. Safety precautions should be taken when handling this substance, as it may cause irritation to skin and eyes.
