It is a colourless solid that is soluble in organic solvents. It is a commercially available reagent for making pinacol boronic esters for organic synthesis. Unlike some other diboron compounds, B2pin2 is not moisture-sensitive and can be handled in air.

Bis(pinacolato)diboron is used as a condensation agent in the preparation poly(arylene)s. Bis(pinacolato)diboron is an organoboranate with potential use as matrix metallo-proteinase (MMP-2) inhibitor.
As a boron source in Pt-mediated diborations, coupling reactions; in Rh-or Ir-mediated borylations of alkanes and arenes, and in carbenoid chemistry.
Bis(pinacolato)diboron or (B2pin2) is the most commonly used diborane reagent in organic synthesis due to its high stability in air and moisture. It can be synthesized by treating tetrakis(dimethylamino)diboron with pinacol in acidic conditions.
