The product we are introducing is 4,4′-Azobis(4-cyanovaleric acid), with the CAS number 2638-94-0. It is provided by our factory at the best price. This compound is an organic peroxide and belongs to the class of azo compounds. It typically appears as a white to off - white powder.
Chemically, its molecular formula is C12H16N4O4, and it has a molecular weight of approximately 280.28 g/mol. It has a relatively high purity level, usually over 98%, which ensures its reliable performance in various applications. The melting point of 4,4′-Azobis(4-cyanovaleric acid) is around 110 - 112°C. It is soluble in some organic solvents such as acetone, chloroform, and ethanol, but has limited solubility in water.
4,4′-Azobis(4-cyanovaleric acid) has a wide range of applications in different industries:
Polymerization Initiator: It is commonly used as a free - radical initiator in the polymerization of various monomers. For example, in the production of polyvinyl chloride (PVC), it can initiate the polymerization reaction, leading to the formation of high - molecular - weight polymers. It can also be used in the synthesis of acrylate polymers, which are widely used in coatings, adhesives, and plastics.
Microsphere Preparation: In the field of materials science, it is used to prepare polymer microspheres. These microspheres can be used in drug delivery systems, chromatography packing materials, and as additives in cosmetics.
Research and Development: In academic and industrial research, it serves as a valuable reagent for studying free - radical reactions and polymer synthesis mechanisms. Scientists can use it to design and develop new polymer materials with unique properties.
Storage: The product should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a well - sealed container to prevent moisture absorption and oxidation. The storage temperature should be maintained between 2 - 8°C.
Handling: When handling 4,4′-Azobis(4-cyanovaleric acid), appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat should be worn. It is recommended to work in a well - ventilated area to avoid inhalation of dust. In case of contact with skin or eyes, immediately rinse with plenty of water and seek medical attention if necessary.
Reaction Conditions: In polymerization reactions, the amount of the initiator added depends on the type of monomer, the desired molecular weight of the polymer, and the reaction temperature. Generally, the initiator concentration is in the range of 0.1 - 1% (w/w) of the monomer. The reaction temperature is usually between 50 - 80°C to ensure an appropriate reaction rate.
Case 1: PVC Production
A plastics manufacturing company was facing challenges in achieving a consistent molecular weight distribution in their PVC products. They decided to switch to 4,4′-Azobis(4-cyanovaleric acid) as the initiator. By carefully controlling the initiator concentration and reaction temperature, they were able to produce PVC with a more uniform molecular weight. This led to improved mechanical properties of the final PVC products, such as better tensile strength and impact resistance. The production efficiency also increased as the reaction time was reduced due to the high activity of the initiator.
Case 2: Drug Delivery Microspheres
A pharmaceutical research team was developing a new drug delivery system using polymer microspheres. They used 4,4′-Azobis(4-cyanovaleric acid) to initiate the polymerization of a biodegradable polymer. The microspheres had a narrow size distribution, which was crucial for the controlled release of the drug. In in - vitro tests, the drug - loaded microspheres showed a sustained release profile, indicating that the use of this initiator was successful in achieving the desired properties of the microsp
