B-2-Dibenzothienylboronic acid (CAS 668983-97-9)

Application and positioning

The sulfur analogue of dibenzofuran-2-boronic acid, used where the higher polarisability of sulfur is wanted in a host or transport material. It couples under standard Suzuki conditions and tolerates the elevated temperatures often used for these rigid substrates. Laurand supplies it from audited Chinese producers in kilogram to multi-tonne lots, with the documentation your market requires.

Quality and documentation
