TCI A0261, N,N'-Bis(2-aminobenzal)ethylenediamine, is a Schiff base compound formed by the condensation of ethylenediamine with two molecules of 2-aminobenzaldehyde. The molecule contains several nitrogen atoms that can donate electron pairs to metal ions, which allows it to act as a chelating ligand. In the TCI catalogue it is listed among the nitrogen-donor ligands used in catalysis and inorganic chemistry. In the laboratory it is used to build coordination complexes with a range of transition metals.
The strength of this type of ligand lies in its chelating structure. The ethylene bridge between the two imine groups forms a framework that can wrap around a single metal ion, while the aromatic amine group at each end adds further donor sites and room for later modification. The resulting complexes can be studied for their spectroscopic, magnetic, and catalytic behavior. Because the imine bond is reversible under certain conditions, the compound is also of interest to researchers working on dynamic covalent chemistry and supramolecular assembly.
For laboratories in Indonesia, the 1 g pack of this TCI product suits inorganic and coordination chemistry research groups that carry out complex synthesis on a small scale. It is also practical for university teaching laboratories, where limited quantities of a specialty ligand are enough to explore ligand design, metal binding, and the characterization of new coordination compounds.

Store the container tightly closed in a cool, dry place away from moisture, heat, and direct light, and follow any storage instruction printed on the supplier's label. Keep it in its original container, or in a clean, dry glass vial with a secure closure if it must be transferred. Because Schiff base imine bonds can be sensitive to water, avoid unnecessary exposure to humid air and reseal the container promptly after use. Handle the material in a well-ventilated area or fume hood, wear gloves, safety glasses, and a laboratory coat, and avoid inhaling dust or contacting skin and eyes. Consult the safety data sheet before use, and dispose of waste according to laboratory and local regulations.
