Preparation and use 1,5-Dihydroxynaphthalene is prepared from naphthalene-1,5-disulfonic acid by hydrolysis with strong base followed by acidification. It couples with various aryl diazonium salts to give diazo dyes. Oxidation with chromium trioxide gives juglone, a naturally occurring dye.2005 Naphthalene Derivatives Ullmann's Encyclopedia of Industrial Chemistry Wiley-VCH Weinheim Booth Gerald 10.1002/14356007.a17_009 3527306730.
