Description

Sodium Mesitylenesulfonate is the sodium salt of mesitylenesulfonic acid, a key sulfonated aromatic compound valued for its surfactant and hydrotropic properties. This chemical is essential for modifying solubility and interfacial activity in complex formulations. It serves as a critical intermediate and additive for manufacturers in the agrochemical, polymer, and specialty chemical industries.

Application

• Hydrotrope and Solubilizer in liquid detergent formulations and hard-surface cleaners.
• Polymerization Aid and emulsifier in the production of specialty polymers and resins.
• Intermediate for the synthesis of dyes, pigments, and other sulfonated aromatic compounds.
• Dispersing Agent in agrochemical formulations for improved stability and efficacy.
• Electroplating Additive for bath stabilization and metal surface refinement.
• Research & Development chemical in organic synthesis and material science.
