Phthalic anhydride is a common laboratory chemical, Pthalic anhydride has been shown to be esterified with primary alcohols at room temperature. Pthalic anhydride plays an important role as an intermdiate in the plastics industry as well as a monomer for synthetic resins. It is also a precursor ot many dyes such as phthalein, phtalocyanine, rhodamine, fluorescein, and xanthene. Phthalic anhydride has also been used in the synthesis of primary amines.
