Description

Disodium 4,4'-Azobis[4-Cyanovalerate] is a water-soluble azo compound widely recognized as a highly efficient free radical initiator. Its primary value lies in its ability to initiate polymerization reactions at relatively low temperatures, making it crucial for processes requiring precise thermal control. This product is essential for manufacturers in the polymer, specialty chemical, and advanced materials sectors who require reliable and consistent initiator performance for producing high-quality acrylic polymers, dispersants, and other functional materials.

Application

• Polymerization Initiator: A key component for the aqueous-phase polymerization of acrylic and vinyl monomers, such as acrylamide, acrylic acid, and their derivatives.
• Dispersant Synthesis: Used in the production of polycarboxylate-based superplasticizers and other high-performance dispersants for the construction industry.
• Surface Coating Resins: Initiates the polymerization for water-based acrylic resins used in paints, adhesives, and textile coatings.
• Hydrogel Production: Facilitates the cross-linking and polymerization in the manufacture of superabsorbent polymers and biomedical hydrogels.
• Paper & Water Treatment Chemicals: Employed in synthesizing flocculants and retention aids for papermaking and wastewater treatment processes.
• Research & Development: Serves as a model initiator in academic and industrial R&D for studying controlled radical polymerization mechanisms.

Quality Control

Our Disodium 4,4'-Azobis[4-Cyanovalerate] is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by HPLC and residual moisture analysis, to ensure it meets the high-purity standards required for sensitive polymerization applications. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent degradation due to moisture absorption. Keep away from heat sources and incompatible materials.
