Product Description

Pyromellitic diimide (CAS 2550-73-4) is an aromatic diimide with the molecular formula C10H4N2O4 and a molecular weight of 216.15. It is supplied as a white to off-white crystalline powder with a melting point above 320 C and an assay of not less than 97%, meeting the requirements of research-grade applications.

The molecule features a rigid, planar benzene core flanked by two imide groups. This structure provides strong electron-accepting ability and pronounced intermolecular hydrogen bonding and pi-pi interactions, which support molecular self-assembly and ordered thin-film formation. These characteristics make pyromellitic diimide a valuable starting material and reference compound in organic semiconductor and functional materials research.

Dideu supplies pyromellitic diimide from 1 g to 1 kg per order, with a lead time within 7 working days. A Certificate of Analysis accompanies each shipment, and packaging is arranged in sealed containers suitable for courier or air transport to global markets.
