Use
Purify corticosterone by recrystallisation from Me2CO (trigonal plates), EtOH or isoPrOH. It has UV max at 240nm, and gives an orange-yellow solution with strong fluorescence on treatment with concentrated H2SO4. It is insoluble in H2O but soluble in organic solvents. [Reichstein Mason et al. J Biol Chem 114 613 1936; ORD: Foltz et al. J Am Chem Soc 7 7 4359 1955; NMR: Shoolery & Rogers J Am Chem Soc 8 0 5121 1958.] The 21-O-acetyl derivative [1173-26-8] crystallises from Me2CO/Et2O with m 152.5-153o, [] D 20 +195o (c 0.6, Me2CO), and the 21-O-benzoyl derivative crystallises from AcOH/Et2O with m 201-202o [Reichstein Helv Chim Acta 2 0 953 1937].
