The Sabanin-Laskowski test for citric acid, the reaction of citric acid with ammonia under pressure, produces a yellow compound which on standing turns blue. This uncommon chemical deportment deserves a study of this almost forgotten chemical test in order to update it, since it has been found that this yellow compound has unique luminescent properties that now are used in nanotechnology and is studied in Organic Chemistry, Physical Chemistry as well as in Biological Chemistry.
