4-Methylindole Chemical Properties, Uses, Production

Chemical Properties

clear yellow to brown liquid after melting

Uses

4-methylindole (4-MID), was selected as a potential liquid organic hydrogen carrier (LOHC) because of its theoretical hydrogen storage density of 5.76 wt%, a melting point of 5 °C and a boiling point of 267 °C [1]. 4-Methylindole serves as a lead activator of the aryl hydrocarbon receptor (AhR), facilitating investigations into its effect on AhR nuclear translocation in LS180 cells[2]. Hydrogenation of 4-methylindole yields octahydro-4-methylindole (8H-4-MID) after solvent distillation[1].
