Description

Azelaic Acid CAS NO 123-99-9 is a naturally occurring saturated dicarboxylic acid, valued for its multifunctional properties and versatility across high-value industries. Its unique structure makes it a critical intermediate for synthesizing polymers, lubricants, and high-performance plasticizers. This compound is essential for manufacturers in the cosmetics, pharmaceuticals, polymer, and specialty chemicals sectors seeking reliable, high-purity raw materials.

Application

• Cosmetic & Dermatological Formulations: A key active ingredient in topical creams and gels for managing skin conditions like acne and rosacea due to its anti-inflammatory and antimicrobial properties.
• Polymer & Plasticizer Production: Serves as a monomer for producing polyamides (nylon-6,9), polyesters, and alkyd resins, and as a precursor for non-phthalate plasticizers like dioctyl azelate.
• Lubricants & Greases: Used in the synthesis of ester-based synthetic lubricants that offer excellent low-temperature performance and thermal stability.
• Corrosion Inhibitors: Employed in metalworking fluids and coatings formulations to provide effective corrosion protection.
• Food Contact Materials: Utilized in the production of polymers approved for food packaging applications.
• Electronics Industry: Finds application in the manufacturing of specialty polymers for electronic components.
