Description

Dodecanedioic Acid, Sodium Salt is the sodium salt derivative of the long-chain dicarboxylic acid, dodecanedioic acid. This compound is valued for its enhanced solubility and stability in aqueous systems compared to its acid form, making it a versatile intermediate and functional additive. It is primarily sought by manufacturers in the polymer, surfactant, and specialty chemical industries for applications requiring precise pH control, emulsification, or as a building block for polyamides and polyesters.

Application

• Polymer Synthesis: As a monomer or co-monomer in the production of specialty nylons (polyamide 6,12), polyesters, and other condensation polymers.
• Surfactants & Detergents: Serving as a key intermediate for the synthesis of anionic surfactants, offering good foaming and wetting properties.
• Corrosion Inhibitors: Used in formulations for metalworking fluids and industrial coolants to provide protective properties.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and drug delivery systems.
• Lubricants & Greases: As an additive or thickener component to modify viscosity and improve performance.
• Cosmetic Ingredients: Functioning as a pH adjuster, emulsifier, or skin-conditioning agent in personal care formulations.
• Chelating Agents: Acting as a precursor for compounds that sequester metal ions in various industrial processes.
• Research & Development: Utilized in chemical research as a standard or reagent for novel material development.
