This compound is a steroidal derivative built upon a 5β-cholan-24-oic acid scaffold. Distinct from obeticholic acid, it possesses a 6β-ethyl substituent, representing an epimer at the C-6 position relative to the parent drug's 6α-ethyl group. Further structural differentiation includes an oxidized carbonyl functionality at the C-7 position, replacing the 7α-hydroxyl group found in obeticholic acid. The 3α-hydroxyl group and the C-24 carboxylic acid are preserved. These specific modifications indicate its potential as a process-related impurity or degradation product. It is primarily utilized as a high-purity reference standard for the identification and quantification of impurities in obeticholic acid drug substance.
