2-Nitrophenylboronic acid (CAS 5570-19-4)

Application and positioning

With the nitro group next to the boronic acid, this is the starting point for 2,2'-dinitrobiphenyls and, after Cadogan cyclisation, for carbazoles. It is the least stable of the three nitro isomers and is best stored cold, dry and protected from light. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

Quality and documentation

• Batch-specific Certificate of Analysis with HPLC purity and water content by Karl Fischer
• 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
• Sealed, dry and protected from light — moisture uptake and oxidation are the main degradation routes
