2-Hydroxyphenylboronic acid (CAS 89466-08-0)

Application and positioning

The ortho-hydroxy group can chelate the boron and pull the molecule into a cyclic boronate form, which is useful when a temporary tether is wanted. It is used for 2-hydroxybiaryls, which cyclise onwards to dibenzofurans and related oxygen heterocycles. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.
