Description

2-[(Potassiooxy)Sulfonyl]Butanedioic Acid Dioctyl Ester is a specialized organosulfur potassium salt derivative of a succinate diester. This compound is valued for its dual functionality, combining anionic surfactant properties with metal ion complexation capabilities. It is primarily sought by manufacturers in the polymer, lubricant additive, and specialty chemical synthesis industries for use as a stabilizer, emulsifier, or intermediate.

Application

• Polymer Additive: Acts as a thermal stabilizer and metal deactivator in PVC and other halogenated polymers.
• Lubricant & Grease Formulation: Serves as an anti-wear additive and corrosion inhibitor in synthetic lubricants and industrial greases.
• Surfactant & Emulsifier: Used in the formulation of specialty detergents, emulsifiers, and dispersion aids for agrochemicals or coatings.
• Chemical Synthesis Intermediate: Employed in organic synthesis for introducing sulfosuccinate groups or as a source of potassium sulfonate.
• Textile & Leather Processing: Functions as a wetting agent, softening agent, or dyeing auxiliary in textile and leather treatment baths.

Quality Control

Our 2-[(Potassiooxy)Sulfonyl]Butanedioic Acid Dioctyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) detailing key parameters such as assay, moisture content, and heavy metals are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality.
