Organic Syntheses, Coll. Vol. 4, p. 824, 1963 - Purification MethodsCrystallise quinoxaline from pet ether. It crystallises as the monohydrate on addition of water to a pet ether solution. It has UV: at 242 and 331nm (Ho –2); 234 and 316nm (pH 7.1). The picrate has m 161-162o.[Albert & Phillips J Chem Soc 1294 1956, Beilstein 23 H 176, 23 II 177, 23 III/IV 1226, 23/7 V 135.]
