Beschreibung

Allgemeine Beschreibung

Cyanogen bromide (CNBr) is a halogen halide. Its utility as a condensing agent during chemical ligation of oligodeoxyribonucleotides has been reported. Its threshold photoelectron (TPE) spectrum has been recorded under high resolution. The cryopolymerization of CNBr on irradiation has been investigated.

Anwendung

Reaction with C₆₀Ph₅Cl produces a novel phenylated isoquinolino[3′,4′:1,2][60]fullerene.

Cyanogen bromide may be used:

• To activate polysaccharides for coupling with erythrocytes.
• As an oxidizing agent in the urine thaimine assay.
• In the preparation of 2-amino-5-(2′-thienyl)-1,3,4-oxadiazole.
