1-(2-Aminoethyl)piperidine is used in modification of vinylbenzyl chloride/divinylbenzene gel copolymer bead and in the synthesis of linkage isomers trans-bis[1-(2-aminoethyl)piperidine]dinitronickel and trans-bis[1-(2-aminoethyl)-piperidine]dinitritonickel. It is also used as a reactant for synthesis of: analogs of anticancer agents, inhibitor of botulinum neurotoxin serotype A light chain, P. falciparum malaria, and Ebola filovirus, cannabinoid CB1 receptor antagonists, small molecules that restore E-cadherin expression and reduce invasion in colorectal carcinoma cells, potent and selective 5-HT6 antagonists and N-mustards as anticancer agents. 1-(2-Aminoethyl)piperidine on [1+1] condensation reaction with 3-methoxy salicylaldehyde yields tridentate Schiff base ligand.
