Diphenolate esters have been used to synthesize epoxy resins as a replacement for the digylcidyl ether of bisphenol A.The digylcidyl ethers of n-alkyl diphenolate esters have similar thermomechanical properties to the digylcidyl ether of bisphenol A when cured but the viscosity and glass transition temperature vary as a function of the ester length. Diphenolate esters have also been used to synthesize polycarbonates with a potential for water solubility.

For R&D use onlynot for drug household or other uses.

Diphenolic acid may be a suitable replacement for bisphenol A as a plasticizer.
