Description

Azelaoyl Chloride is a versatile bifunctional acid chloride derived from azelaic acid, serving as a key reactive intermediate in organic synthesis. Its value lies in its ability to efficiently introduce the azelaoyl moiety, enabling the creation of polymers, plasticizers, and specialty chemicals with tailored properties. This compound is essential for manufacturers in the polymer, agrochemical, and pharmaceutical industries seeking to develop products with specific chain lengths and functionalities.

Application

• Polymer Synthesis: A crucial monomer for producing polyamides (nylon 6,9), polyesters, and other condensation polymers, imparting flexibility and specific physical properties.
• Plasticizer Production: Used in the manufacture of ester-based plasticizers, such as dioctyl azelate (DOZ), which offer excellent low-temperature performance for PVC and synthetic rubbers.
• Agrochemical Intermediates: Serves as a building block for synthesizing herbicides, fungicides, and plant growth regulators.
• Pharmaceutical Synthesis: Employed in the production of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring the azelaic acid backbone.
• Lubricant & Grease Additives: Used to create synthetic esters that enhance the performance and stability of high-end lubricants and functional fluids.
• Corrosion Inhibitors: Acts as a precursor for compounds that form protective layers on metal surfaces.
• Surface Active Agents: Intermediate for the production of surfactants and emulsifiers with specific hydrophobic chain characteristics.
• Specialty Chemical Synthesis: A key reagent for organic chemists in research and development for creating novel compounds, dyes, and flavor/fragrance ingredients.

Quality Control

Our Azelaoyl Chloride is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your technical requirements and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, ignition sources, and incompatible materials. Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature: 2-8°C. Keep away from strong bases, alcohols, and water.
