Catecholborane

Catecholborane (CAS 274-07-7, EC 205-991-5), also known as catecholatoborane, pyrocatecholborane, and 1,3,2-benzodioxaborole, is a cyclic organoboron compound with the molecular formula C6H5BO2. It functions as a selective hydroboration reagent, delivering boron across unsaturated bonds under mild conditions.

In pharmaceutical synthesis, catecholborane reduces imines and carbonyl groups with high chemoselectivity, enabling the construction of chiral amine intermediates used in active pharmaceutical ingredient manufacturing. In polymer chemistry, it initiates controlled radical polymerization sequences and serves as a boron transfer agent in the preparation of boronate-functionalized monomers for specialty materials.

Catecholborane is supplied under REACH compliance and is available in research and commercial quantities from European stock. Standard packaging includes sealed glass or metal containers under inert atmosphere to maintain stability. Procurement teams should confirm purity grade and handling specifications with our technical team prior to ordering.
