Pyromellitic dianhydride (PMDA) ndizofunikira kwambiri pamakampani opanga ma organic synthesis, komanso zopangira zopangira zida zatsopano zamakina ndi mankhwala owonjezera amtengo wapatali. Amagwiritsidwa ntchito kwambiri popanga polyimide monomers, ndipo amathanso kugwiritsidwa ntchito ngati Chithandizo cha epoxy resin ndi cholumikizira cholumikizira cha polyester resin, chomwe chimagwiritsidwa ntchito popanga utoto wa buluu wa phthalocyanine ndi zotumphukira zina zofunika, ndi zina zambiri. ntchito zosiyanasiyana. Pyromellitic dianhydride, yomwe imadziwikanso kuti homoanhydride, ili ndi mawonekedwe apadera a maselo ndipo ingagwiritsidwe ntchito popanga zipangizo zowonongeka ndi kutentha, kutsekemera kwa magetsi ndi kukana kwa mankhwala, zomwe zimagwiritsidwa ntchito kwambiri ngati monolayer wa polyimide. Amapangidwa ndi diamine onunkhira kuti apeze pulasitiki ya polyimide, koma chiyero cha pyromellitic dianhydride ndichokwera kwambiri, chomwe chiyenera kukhala choposa 99%.
