This category of Linear Diamines and Hyrazinesincludes around 100 building blocks with diamine and hydrazine functional groups, respectively. Especially vicinal diamines (1,2-diamines) appear as structural motif in biological compounds and are used as ligands in coordination chemistry. Hydrazines contain two covalently linked nitrogen atoms which carry hydrogen atoms, alkyl, or aryl substituents. Iris Biotech GmbH supplies variously substituted diamines and hydrazines with different spacer lengths and a large selection of protection groups.
