5-ALPHA-PREGNANE Usage And Synthesis
Uses
Pregnane is the steroid fundamental parent. A parent of the progesterone.
Definition
ChEBI: 5alpha-pregnane is a pregnane and a C21-steroid.
Purification Methods
Recrystallise 5-pregnane several times from Me2CO. The melting point is lowered (e.g. to 50-71o) if it is contaminated with the 5-isomer. [Butenandt et al. Chem Ber 6 4 2529 1931, Steiger & Reichstein Helv Chim Acta 21 161 1938, Beilstein 5 III 1120, 1121, 1125.]
