CAS 97-72-3

Isobutyric anhydride

Description:

Isobutyric anhydride, with the CAS number 97-72-3, is an organic compound that serves as a derivative of isobutyric acid. It is characterized by its anhydride functional group, which is formed by the condensation of two molecules of isobutyric acid, resulting in the loss of water. This compound typically appears as a colorless to pale yellow liquid with a pungent odor. Isobutyric anhydride is known for its reactivity, particularly in acylation reactions, where it can introduce isobutyric acyl groups into various substrates. It is soluble in organic solvents but has limited solubility in water. Due to its chemical properties, it is utilized in the synthesis of esters, amides, and other derivatives in organic chemistry. Safety precautions are essential when handling this compound, as it can be irritating to the skin, eyes, and respiratory system. Proper storage in a cool, dry place away from incompatible materials is also recommended to ensure stability and safety.

Isobutyric anhydride

CAS: 97-72-3

Isobutyric anhydride is a crystalline cellulose-derived chemical that is used as a solvent in pharmaceutical preparations. It is also used as a reactive agent in the production of antibiotics. Isobutyric anhydride reacts with the hydroxyl group on the antibiotic to form an ester, which in turn reacts with trifluoroacetic acid to form the final product. The mechanism of this reaction is kinetic and hydrochloric acid can be used as a catalyst. Isobutyric anhydride has been shown to have high reactivity with antibiotic-resistant strains of bacteria. This compound has high bioavailability when administered orally and exhibits high kinetic constants for both hydrolysis and esterification reactions, making it a useful drug for preventing bacterial growth in vivo.
