1,2,4,5-cyclohexanetetracarboxylic dianhydride (HPMDA) CAS 2754-41-8

An alicyclic dianhydride building block

For polyimides and polyesters synthesis to be applied as photochromic materials, proton conducting membranes, and bioimaging polymers

Specifications | MSDS | Literature and Reviews

1,2,4,5-Cyclohexanetetracarboxylic dianhydride (HPMDA, CAS number 2754-41-8) has a cyclohexane centre with two carboxylic anhydrides substituents sitting opposite to each other. HPMDA reacts with amines for polyimides or alternatively with alcohols for polyesters. The non-aromatic cyclohexane centre provides local excited state to the synthesized photochromic polyimides showing large contrast of the photo-switching effect (compared to fully aromatized polyimides). The polyimides derived from 1,2,4,5-cyclohexanetetracarboxylic dianhydride exhibit high proton conductivity (0.2 ± 0.01 S/cm at 298 K and 95% related humidity). Like other polyimides, the polyimides have excellent chemical and thermal resistance and are used in optical fibre claddings and substrates for microelectronics.

HPMDA can be used to synthesize polyesters that have four branches (dianhydride is hydrolysed to four carboxylic acids) for multiple functionalities, such as biodegradability, bioimaging and photoactivity.
