4-(naphthalene-1-yl)phenylboronic acid (CAS 870774-25-7)

Application and positioning

A phenylboronic acid that already carries a 1-naphthyl group, so the coupling installs a naphthyl-phenyl arm in one operation. It is used to build extended aromatic systems in which the naphthalene is held at an angle to the main axis. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.
