Request Quote4,4′-Azobis(4-cyanovaleric acid) is a premium-grade, water-soluble azo initiator extensively used in polymer chemistry, materials science, and advanced chemical synthesis. This high-purity radical initiator (>98.0%) offers exceptional thermal stability and controlled decomposition kinetics, making it an indispensable reagent for precise polymerization reactions in both research and industrial applications. Unlike hydrophobic azo initiators such as AIBN (Azobisisobutyronitrile), 4,4′-Azobis(4-cyanovaleric acid) features carboxylic acid functional groups that provide excellent solubility in water and polar solvents. This unique characteristic enables its use in emulsion polymerization, aqueous-based polymer synthesis, and biocompatible material development where traditional initiators are ineffective. The compound generates free radicals at predictable rates when heated (typically at 60-70°C), allowing researchers and manufacturers to achieve consistent, reproducible polymerization results with controlled molecular weight distributions. Its reliability and versatility have made it a standard choice in pharmaceutical manufacturing, biotechnology, specialty coatings, and advanced materials production.
