Factory Supply Isobutyric Anhydride Cas 97 - 72 - 3 With Good Price is a chemical product that has gained significant attention in various industries. The CAS number 97 - 72 - 3 uniquely identifies this compound. Isobutyric anhydride has the molecular formula of (CH₃)₂CHCO₂COCH(CH₃)₂ and a molecular weight of approximately 158.19 g/mol. It appears as a clear, colorless to pale - yellow liquid with a pungent odor. This product is commonly available in high - purity grades, ensuring its quality and suitability for different applications. The boiling point of isobutyric anhydride is around 182 - 184 °C, and its density is about 0.963 g/mL at 25 °C. It is slightly soluble in water but miscible with many organic solvents such as ethanol, ether, and benzene.
Isobutyric anhydride serves a wide range of uses in multiple industries. In the pharmaceutical industry, it is used as an intermediate in the synthesis of various drugs. It can react with other chemical compounds to form new molecules with desired biological activities. For example, it can be used in the production of antibiotics and anti - inflammatory drugs. In the fragrance and flavor industry, isobutyric anhydride is a key raw material. It imparts a characteristic, slightly fruity and pungent odor, which can be used to create unique fragrance compositions. In the food industry, it is used as a flavoring agent in small amounts to add a specific taste note to food products. Additionally, it is used in the synthesis of plastics, resins, and other polymer materials, where it can act as a cross - linking agent or a modifier to improve the properties of the final products.
When using isobutyric anhydride, it is crucial to follow proper safety protocols. Always wear appropriate personal protective equipment, including gloves, safety goggles, and a lab coat. First, ensure that the storage conditions are suitable. It should be stored in a cool, dry place away from sources of heat and direct sunlight. Before use, check the purity and quality of the product to ensure that it meets the requirements of your specific application. When handling the liquid, use a suitable container and transfer it carefully to avoid spills. In chemical synthesis, accurately measure the amount of isobutyric anhydride required according to the reaction stoichiometry. Add it slowly to the reaction mixture while stirring continuously to ensure uniform mixing and proper reaction. After use, clean all equipment thoroughly with appropriate solvents to prevent contamination and corrosion.
1. Pharmaceutical Synthesis: A pharmaceutical company was developing a new antibiotic. They used isobutyric anhydride as an intermediate in the multi - step synthesis process. By reacting it with a specific amine compound, they were able to form a key intermediate with high yield and purity. The reaction conditions were carefully optimized, including temperature, reaction time, and the molar ratio of reactants. After further purification and subsequent reactions, the final antibiotic product met all the quality and efficacy requirements. The use of isobutyric anhydride in this process was crucial for the successful synthesis of the new drug.
2. Fragrance Creation: A perfume house wanted to create a new fragrance with a unique, fruity - pungent note. They incorporated isobutyric anhydride into their fragrance formula. After several rounds of formulation and testing, they found that a specific concentration of isobutyric anhydride could enhance the overall character of the fragrance. The new fragrance was well - received in the market, attracting consumers who were looking for something different and exciting in the perfume industry.
3. Polymer Modification: A plastics manufacturer was trying to improve the mechanical properties of a certain type of resin. They added isobutyric anhydride as a modifier during the polymerization process. The addition of isobutyric anhydride led to an increase in the cross - linking density of the resin, resulting in improved strength, hardness, and heat resistance. The modified resin was then used to produce high - quality plastic products for automotive and electronic applications.
