CAS 13222-85-0: 4-Methylbenzene-1-Carboxylic Anhydride

Description:4-Methylbenzene-1-Carboxylic Anhydride, also known as 4-Methylphthalic anhydride, is an organic compound characterized by its anhydride functional group derived from 4-methylbenzoic acid. It typically appears as a colorless to pale yellow solid and has a distinctive aromatic odor. This compound is known for its reactivity, particularly in undergoing hydrolysis to form the corresponding carboxylic acid upon exposure to moisture. It is used in various applications, including as an intermediate in the synthesis of dyes, resins, and pharmaceuticals. The presence of the methyl group enhances its solubility in organic solvents, making it useful in various chemical processes. Additionally, 4-Methylbenzene-1-Carboxylic Anhydride can participate in electrophilic aromatic substitution reactions due to the electron-donating nature of the methyl group. Safety precautions should be observed when handling this compound, as it can be irritating to the skin and respiratory system. Proper storage in a cool, dry place away from moisture is essential to maintain its stability and reactivity.
