Use
Recrystallise D-thyroxine from H2O (needles) or from an ammonical solution by dilution with H2O, MeOH or Me2CO. It has also been purified by dissolving ~6.5 g in a mixture of MeOH (200mL) and 2N HCl (20mL), adding charcoal, filtering then adding NaOAc solution to pH 6. On standing the thyroxine separates, it is filtered off, washed with MeOH then Me2CO and dried in vacuo. N-Formyl-D-thyroxine has m 210o and [] 21 -26.9o (c 5, EtOH). (±)-Thyroxine has m 256o and is purified in the same way. [Nahm & Siedel Chem Ber 96 1 1963, Salter Biochem J 24 471 1930, Beilstein 14 I 671, 14 II 384, 14 III 1566, 14 IV 2374.]
