Description

Disodium 4',4'''-Azobis[1,1'-Biphenyl]-4-Carboxylate is a high-purity, water-soluble azo compound derivative that serves as a critical intermediate and functional material in advanced chemical synthesis. Its primary value lies in its ability to act as a photoinitiator or a precursor for generating radicals under specific conditions, enabling precise control in polymerization and cross-linking processes. This product is essential for manufacturers in the polymer, specialty coatings, and advanced material sectors seeking reliable, high-performance chemical components for research and production.

Application

• Photoinitiator in Polymer Chemistry: Used to initiate free-radical polymerization in UV-curable resins, inks, and coatings.
• Cross-linking Agent: Facilitates the formation of polymer networks to enhance the thermal and mechanical properties of specialty plastics and elastomers.
• Research & Development: Serves as a key intermediate in organic synthesis and material science research for developing novel functional polymers.
• Advanced Material Production: Employed in the manufacture of high-performance adhesives, sealants, and composite materials requiring controlled curing.
• Dye and Pigment Intermediate: Acts as a building block in the synthesis of specific azo dyes and functional colorants.

Quality Control

Our Disodium 4',4'''-Azobis[1,1'-Biphenyl]-4-Carboxylate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, IR for identification, and loss on drying for moisture content. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which may affect product performance.
