CLEAR VERY SLIGHTLY YELLOW TO YELLOW LIQUID

N-Isopropylbenzylamine was used as ligand in the preparation and characterization of bis(cyclopentadienyl)magnesium. It was also used in the synthesis of N-benzylideneisopropylamine-N-oxide.

N-Isopropylbenzylamine is an organic intermediate, which can be obtained by reduction of N-isopropylbenzamide or by reductive amination of benzylamine and acetone.

The toxicity of N-isopropylbenzylamine was evaluated in SH-SY5Y, PC12, and SN4741 cell lines. Cells were treated with 0.3–10 mM N-isopropylbenzylamine for 24 hours, and cell viability was measured using MTT assay. N-isopropylbenzylamine concentration-dependently reduced cell viability in these cells. The IC50 values of N-isopropylbenzylamine on cell viability were 3.47, 1.49, and 3.21 mM for SH-SY5Y cells, PC12 cells, and SN4741 cells, respectively. N-isopropylbenzylamine produced toxicity in cell lines that model neurons. Moreover, the activation of nNOS and the production of intracellular NO might be involved in N-isopropylbenzylamine-induced toxicity in SN4741 cells[1].
