Description
9-Methoxy-9-BBN (CAS 38050-71-4), also known as 9-MeO-9-BBN, B-Methoxy-9-BBN, and 9-Methoxy-BBN, is an organoborane compound derived from 9-BBN in which a methoxy group occupies the boron centre. It carries no assigned E-code and is classified within the catalysts and catalyst precursors category.
In pharmaceutical synthesis, 9-Methoxy-9-BBN serves as a hydroboration reagent and boron-transfer agent, delivering controlled regioselectivity in the preparation of chiral intermediates and active pharmaceutical ingredients. In biotechnology applications, it functions as a catalyst precursor in cross-coupling reactions, activating boron centres for selective carbon-carbon bond formation under mild conditions.
This compound is supplied as a liquid and is subject to REACH registration requirements applicable within the European Economic Area. Procurement teams should confirm purity grade specifications and packaging formats directly with the supplier, as these vary according to application requirements and order volume.
