Application
1. 4,4'-Azobis(4-cyanovaleric acid) is a water-soluble azo initiator used to generate carboxyl-functionalized free radicals for polymerization reactions, such as the synthesis of polyacrylonitrile (PAN) with improved hydrophilicity .
2. 4,4'-Azobis(4-cyanovaleric acid) CAS 2638-94-0 is employed in biomedical research as a thermosensitive linker in drug delivery systems, enabling controlled release of therapeutic agents under alternating magnetic fields .
3. 4,4'-Azobis(4-cyanovaleric acid) serves as a peroxyl radical source in oxidative stress studies to investigate damage to biomolecules like hemoglobin and tryptophan .
Storage and Precautions
1. Store 4,4'-Azobis(4-cyanovaleric acid) in a tightly sealed container under inert gas at refrigerated temperatures (2-8°C) to maintain stability and prevent decomposition .
2. Keep 4,4'-Azobis(4-cyanovaleric acid) CAS 2638-94-0 strictly away from heat, sparks, open flames, and strong oxidizing agents due to its flammable solid classification (H228) .
3. Handle 4,4'-Azobis(4-cyanovaleric acid) using appropriate personal protective equipment including chemical-resistant gloves and safety goggles, and work in a well-ventilated area to avoid dust generation .
Emergency response to leakage
1. Isolate the spill area, eliminate all ignition sources, and use non-sparking tools to sweep solid 4,4'-Azobis(4-cyanovaleric acid) into sealed, labeled containers for disposal .
2. Prevent spilled 4,4'-Azobis(4-cyanovaleric acid) CAS 2638-94-0 from entering drains or waterways, as discharge into the environment must be strictly avoided.
3. Personnel cleaning 4,4'-Azobis(4-cyanovaleric acid) spills must wear full protective equipment including suitable respirator and dispose of waste according to hazardous material regulations (UN3226, Class 4.1, PG II) .
Safety Information
1. 4,4'-Azobis(4-cyanovaleric acid) is a flammable solid (H228) with GHS signal word "Danger" or "Warning" depending on classification, and may decompose exothermically upon heating .
2. 4,4'-Azobis(4-cyanovaleric acid) CAS 2638-94-0 causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
3. Combustion of 4,4'-Azobis(4-cyanovaleric acid) produces toxic fumes including carbon oxides and nitrogen oxides; 4,4'-Azobis(4-cyanovaleric acid) has a melting point of 118-125°C and density of 1.23 g/cm³ .
