PHTHALIC ANHYDRIDE, EXTRA PURE

Phthalic Anhydride, Extra Pure is a white flake and is soluble in water to form corresponding acidic derivatives. It is the cyclic anhydride of phthalic acid and serves as its principal commercial form. Its structure enables it to react with various compounds to give a variety of derivatives. It is used as a precursor in the production of pigments and dyes, in the development of color-imparting compounds. It is also used in the production of agricultural and pharmaceutical products and chemical formulations. Its ability to form many derivatives makes this compound an important building block both in the industrial and laboratory synthesis.

A key intermediate used in the production of dyes, pigments, and various chemical products.
