Description

Clear Colourless to Pale Yellow Oil 4,6,6,7,8,8-Hexamethyl-1,3,4,6,7,8-hexahydrocyclopenta[g]benzopyran is a viscous liquid with a musk-like odor. It is one of the most frequently used synthetic, artificial musk fragrances.The starting material for its synthesis is 1,1,2,3,3-pentamethylindane, which is prepared by cycloaddition of tert-amylene to α-methylstyrene. The pentamethylindane is hydroxyalkylated with propylene oxide in a Friedel–Crafts reaction using aluminum chloride as a catalys
