2-Cyanophenylboronic acid (CAS 138642-62-3)

Application and positioning

The ortho-cyano group survives the coupling and can then be hydrolysed to an amide or acid, or reduced to an aminomethyl group. It is the standard route to 2-substituted benzonitriles, the structural core of the biphenyl sartan family. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

Quality and documentation

• 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
