Description

2,5-Dihydroxy-4-Pentadecylbenzenesulfonic Acid Sodium Salt is a specialized anionic surfactant and intermediate with a unique hydrophobic-hydrophilic balance derived from its long alkyl chain and sulfonate group. This compound matters for its ability to modify surface properties, acting as a wetting agent, emulsifier, or dispersant in complex formulations. It is needed by manufacturers in the chemical synthesis, specialty surfactant, and advanced material sectors for developing high-performance products.

Application

• As a key intermediate in the synthesis of specialty surfactants and dyes.
• As a wetting and dispersing agent in pigment preparations and coating formulations.
• As an emulsifier in specialized industrial and agrochemical emulsions.
• In research and development for novel polymeric materials and surface-active compounds.
• As a stabilizing agent in certain colloidal systems and latex applications.
• Potential use as a corrosion inhibitor component in functional fluid formulations.
