Borane dimethyl sulfide complex

Borane dimethyl sulfide complex (CAS 13292-87-0, EC 236-313-6), also known as DMSB or borane dimethylsulfide, is an organoboron reagent supplied as a stabilised borane source in which dimethyl sulfide acts as a Lewis base ligand, moderating the reactivity of the borane and enabling controlled handling and delivery of boron hydride chemistry.

In pharmaceutical synthesis, DMSB serves as a selective reducing agent for carboxylic acids, amides, and oximes under mild conditions, delivering the borane moiety without the hazards of diborane gas. In polymer chemistry, it initiates hydroboration-based polymerisation sequences, enabling the construction of boron-functionalised polymer architectures used in specialty coatings and functional materials.

This product is supplied as a clear solution and is registered under REACH. It is handled under standard protocols for pyrophoric and moisture-sensitive reagents, and procurement should confirm concentration grade and packaging format directly with the supplier to meet specific formulation requirements.
