Diboron Tetrahydroxide is extensively used in Suzuki-Miyaura cross-coupling reactions as a boron source for aryl and vinyl couplings. In material science, it facilitates the synthesis of boron-doped graphene and other advanced carbon matrices. Researchers also employ it as a mild reducing agent in organic transformations, such as selective carbonyl reductions. Its stability under controlled conditions makes it suitable for catalytic systems in polymer chemistry.
