(4-bromonaphthalen-1-yl)boronic acid (CAS 145965-14-6)

Application and positioning

A naphthalene carrying bromine at C4 and a boronic acid at C1, giving two orthogonal coupling sites on the same ring system. It is used to extend conjugation in both directions, for example in OLED emitters and in naphthalene-linked pharmaceutical scaffolds. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.
