Description

Application

Sodium benzenesulfonate has been used in Raman spectroscopic determination of molecular structural features in sulfonated polystyrene resins. It was used as electrolyte in formation of polypyrrole coatings with varying surface morphology on stainless steel. It was used in the synthesis of 1-butyl-3-propanenitrile imidazolium benzenesulfonate.
