(4-phenylnaphthalen-1-yl)boronic acid (CAS 372521-91-0)

Application and positioning

A 1-naphthylboronic acid with a phenyl already fixed at the 4-position, so the coupling adds the second aryl group without an extra step. It is used for 1,4-diarylnaphthalenes, a motif found in blue-emitting materials and in rigid fluorophores. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

• Anhydride content reported per lot, since arylboronic acids equilibrate with their anhydride form
• SDS in the language of your market, with GHS classification for the destination
• Pre-shipment sample for laboratory approval on first orders

Packaging and handling

• 1 kg, 5 kg and 25 kg fibre drums with inner PE liner; pack size confirmed at quotation
