Useful:

• Uses: Diphenylborinic Anhydride is used a a photopolymerization co-initiator. Diphenylborinic anhydride (DPBA) may be used for the separation and determination of α-amino acids by boroxazolidone formation. DPBA, an analogue of the vascular gap junction channel blocker, 2-aminoethoxydiphenyl borate (2-APB), may be use in gap junctions channel studies.
