3β-11α-17-TRIHYDROXY-5-PREGNEN-20-ONE 11-HEMISUCCINATE AS A HAPTENE FOR RIA OF ''17α-HYDROXYPREGNENOLONE''

6β,17-Dihydroxy-3α,5-cyclo-5α-pregnan-20-one (VII) and 17-hydroxy-6β-methoxy-3α,5-cyclo-5α-pregnan-20-one (IX) were hydroxylated into the position 11α using Rhizopus nigricans fungi culture, and then selectively converted into haptene XIII for the RIA determination of 3β,17-dihydroxypregn-5-en-20-one (IV).
