description Product Description
Ethanesulfonic acid is a strong organic acid primarily employed as a catalyst in organic synthesis reactions, such as esterification, transesterification, and polymerization. It functions as an intermediate in the production of pharmaceuticals, agrochemicals, dyes, and surfactants. In electroplating, it is used in bath solutions to enhance conductivity, improve deposit uniformity, and act as a leveling agent. Additionally, it serves as a component in electrolytes for batteries and capacitors, contributing to better stability and performance. Its robust acidic properties render it essential in laboratory research and industrial manufacturing.
