Description

Application

1,4,7-Triazacyclononane trihydrochloride can be used as a reagent to prepare:

• Nonadentate ligand, 1,4,7-tris[(6-carboxypyridin-2-yl)methyl]-1,4,7-triazacyclononane (H3tpatcn), which is used to prepare lanthanide complexes with high water solubility and rigid C₃ symmetric structures.
• Dansyl cryptands as fluorescent indicators via amination of (bromobenzyl)triazacycloalkane and oxadiamines.
• [1,4,7-tri(3-butenyl)-1,4,7-triazacyclononane and 1,4,7-tri(2-propenyl)-1,4,7-triazacyclononane] by reacting with corresponding alkenyl halide.

Possible reagent for compleximetric titrations with high cation-binding selectivity.
