2-Methyl-1-tetralone Usage And Synthesis

Chemical Properties

clear yellow to orange liquid

Uses

Methylation of 1-tetralone followed by the subsequent dehydrogenation of 2-methyl-1-tetralone in the presence of Pd/C catalyst also has been reported.

Definition

ChEBI: 2-methyl-1-tetralone is a member of the class of tetralins that is tetralin in which the hydrogens at positions 1 and 2 are replaced by oxo and methyl groups, respectively. It is a member of tetralins and an aromatic ketone.
