Ammonia borane

Ammonia borane (CAS 13774-81-7, EC 642-983-4, formula BH6N), also known as borazane or ammineborane, is a boron-nitrogen hydride compound classified as a catalyst precursor. It carries no assigned E-code and is distinct from elemental boron sources, offering a molecularly bound hydrogen content that makes it chemically reactive under controlled conditions.

In pharmaceutical synthesis, ammonia borane serves as a selective reducing agent, transferring hydride to carbonyl and imine functional groups under mild conditions without requiring high-pressure hydrogen equipment. In electronics manufacturing, it functions as a hydrogen source for chemical vapour deposition processes, releasing H2 at defined temperatures to deposit boron-containing thin films with controlled stoichiometry.

Ammonia borane is supplied as a white solid in research and technical grades, compliant with REACH registration requirements applicable to European importers and downstream users. Packaging is typically available in sealed inert-atmosphere containers ranging from 25 g laboratory quantities to multi-kilogram industrial formats. Buyers should confirm grade specifications against application purity thresholds prior to ordering.
