Description

Sodium Hydrogen Azelate is the monosodium salt of azelaic acid, a naturally occurring dicarboxylic acid. This specialty organic salt is valued for its role as a versatile intermediate and functional additive in high-performance formulations. It is particularly relevant for industries requiring precise pH adjustment, buffering, or the introduction of a medium-chain dicarboxylate moiety. Key sectors that utilize this compound include polymer synthesis, personal care, and advanced material science.

Application

• Polymer & Resin Manufacturing: Acts as a monomer or chain modifier in the synthesis of polyesters, polyamides, and alkyd resins, contributing to flexibility and specific material properties.
• Personal Care & Cosmetics: Serves as a buffering agent and a precursor in skincare formulations, leveraging the beneficial properties associated with azelaic acid derivatives.
• Lubricants & Greases: Used in the production of synthetic ester-based lubricants and metalworking fluids as a corrosion inhibitor and additive component.
• Chemical Synthesis: Functions as a key organic intermediate for producing esters, amides, and other derivatives used in fragrances, plasticizers, and specialty chemicals.
• Textile & Leather Processing: Employed as a pH regulator and auxiliary agent in dyeing and finishing processes.
• Laboratory & Research: Used as a standard or reagent in analytical chemistry and biochemical research applications.

Quality Control

Our Sodium Hydrogen Azelate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise chemical and physical specifications, including identity, purity, and impurity profiles. While available in standard technical and purified grades, production can be aligned with specific customer requirements. A Certificate of Analysis (COA) detailing the results of our comprehensive quality tests is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
