Abstract: The title compound, C₂₁H₂₉BrO₃·CH₃OH, is a steroid and an intermediate for medicinal applications. It is prepared through the reaction of 16,17-epoxypregn-4-ene-3,20-dione and HBr, and the methanol solvate is reported here. The space group is $P2_{1}2_{1}2_{1}$ and is different from the space group of 16 [beta] -bromo-17 [alpha] -hydroxypregn-4-ene-3,20-dione which is C2 [Wang, Wang, Nie, Xiang & Zhou (2005).
