4-Methoxyphthalic anhydride

Description:

4-Methoxyphthalic anhydride, with the CAS number 28281-76-7, is an organic compound characterized by its anhydride functional group derived from phthalic acid. It appears as a white to light yellow crystalline solid and is known for its moderate solubility in organic solvents such as acetone and ethyl acetate, while being less soluble in water. This compound is primarily used in the synthesis of various polymers and resins, particularly in the production of epoxy and polyester materials, due to its ability to act as a hardener or crosslinking agent. Its chemical structure features a methoxy group (-OCH3) attached to the aromatic ring, which influences its reactivity and properties. 4-Methoxyphthalic anhydride is also noted for its potential applications in the field of coatings and adhesives. As with many chemical substances, handling should be done with care, following appropriate safety guidelines to mitigate any health risks associated with exposure.
