2-(4-Methoxyphenyl)ethanol is used as an internal standard in the fluorous biphasic catalysis reaction. It is used in the preparation of 4-(2-iodoethyl)phenol, by refluxing it with 47% hydriodic acid. It may be used in the preparation of (2R*,4R*)-1-n-butyl-2-methyl-4-(2-oxopyrrolidin-1-yl)-6-methoxy-1,2,3,4-tetrahydroquinoline and (2R*,4S*)-1-n-butyl-2-methyl-4-(2-oxopyrrolidin-1-yl)-6-methoxy-1,2,3,4- tetrahydroquinoline. It is used for foods, perfumes, and cosmetics.
