Application

Be used as pharmaceutical intermediate.

The bis-pinacol borate is a boron compound containing two pinacol structures. This compound is a commercially available reagent and is a commonly used substrate in organic synthesis for the preparation of various pinacol borate esters.

Cis-complex boronation reagent for acetylene and paraffin (platinum catalysis).

Palladium catalyzed boronation of aromatic compounds.

Palladium-catalyzed cyclization of 1,6-enyne produces a substrate in the reaction of homogeneously alkylboronates.

Package: 25kg/drum, can also be designed according to customer requirements.

Storage: Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
