4′-Aminobenzo-18-crown-6（Cat No.:L021872）is a functionalized macrocyclic polyether belonging to the crown ether family, featuring an 18-crown-6 ring with a para-amino-substituted benzene moiety attached. This compound combines the selective cation-binding ability of 18-crown-6—especially for potassium and ammonium ions—with the reactive amino group, enabling further chemical derivatization or immobilization on solid supports. It is widely used in host–guest chemistry, ion transport studies, sensor development, and as a phase-transfer catalyst. Its ability to form stable complexes with alkali metals makes it useful in analytical, supramolecular, and materials chemistry applications.
