[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is an inorganic compound used as a reagent in molecular biology.  As a reagent for peptide mapping and amino acid sequence analysis, cyanogen bromide hydrolyzes peptide bonds at methionine residues in peptides and proteins.  In addition, this agent acts as a coupling reagent for phosphoramidate or pyrophosphate inter-nucleotide bonds in DNA duplexes. (NCI)"}, {"from": "gpt", "value": "[C][#Branch1][C][#N][Br]"}]
