Pyromellitic dianhydride

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 208543

CAS#: 89-32-7

Description: Anhydrides are widely used as cross-linking agents in epoxy resins and alkyd production, for example, as coatings and adhesives in plastic products. Sensitisation to several anhydrides is known to cause occupational asthma. There are indications that the lesser known pyromellitic dianhydride (PMDA) can cause irritative respiratory symptoms and possibly asthma. Recently, researches found crosslinking pyromellitic dianhydride (PMDA) with cyclodestrin polymers have been found to have anti-HIV-1 activity
