General description
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.
Application
用于肽的断裂和用于蛋白质固化过程。与 C60Ph5Cl 反应生成新型苯代异喹啉并[3′,4′:1,2][60]富勒烯。
Cyanogen bromide may be used:
- To activate polysaccharides for coupling with erythrocytes.
- As an oxidizing agent in urine thaimine assay.
- In the preparation of 2-amino-5-(2′-thienyl)-1,3,4-oxadiazole.

Cyanogen bromide was found to condense oligodeoxyribonucleotides on a complementary template in aqueous solution. Optimum conditions for this vigorous and effective reaction were developed. CNBr proved to be useful for incorporation of phosphoramidate or pyrophosphate internucleotide bonds in DNA duplexes.
