Tetrahydromethyl-1,3-isobenzofurandione CAS 11070-44-3

A series of carbon rings and heterocyclic compounds can be obtained by continuous conversion of phthalic anhydride units. Methyltetrahydrophthalic anhydride reacts with ammonia or primary amine to obtain methyltetrahydrophthalimide, which has antihypertensive and anticonvulsant effects.Methyltetrahydrophthalic anhydride is an intermediate used in pharmaceuticals, polymers, dyes, and plasticizers. Methyltetrahydrophthalic anhydride derivatives in drug synthesis can be synthesized by conversion of the anhydride unit.
