Description

Dipotassium Sebacate is the dipotassium salt of sebacic acid, a valuable dicarboxylate compound. This high-purity chemical intermediate is essential for applications requiring a stable, water-soluble source of sebacate ions. It serves critical functions in the pharmaceutical industry as an excipient and buffering agent, and in industrial sectors for polymer synthesis and corrosion inhibition. Global manufacturers and R&D facilities rely on its consistent quality for advanced material development and formulation stability.

Application

• Pharmaceutical Excipient: Used as a buffering agent, stabilizer, or counterion in tablet and capsule formulations.
• Polymer Synthesis: Acts as a monomer or chain extender in the production of polyesters, polyamides, and other specialty polymers.
• Corrosion Inhibitor: Formulated into aqueous-based anti-corrosion treatments and metalworking fluids.
• Laboratory Reagent: Serves as a standard or analytical reagent in chemical analysis and research.
• Personal Care Formulations: Utilized as a pH adjuster and chelating agent in select cosmetic and personal care products.
• Food Additive (Potassium Source): Can function as a source of potassium and a pH control agent in certain food-grade applications (subject to compliance).
