3alpha,12alpha-Dihydroxy-5beta-chol-9(11)-enic Acid is a tetracyclic steroid acid derivative characterized by a 5beta-cholane skeleton with hydroxyl groups at C-3 and C-12 in alpha-configuration, and a conjugated double bond between C-9 and C-11 in the B ring. Its structural features align with bile acid metabolism pathways, exhibiting a 5beta-hydroxylated configuration and a terminal carboxylic acid. This compound serves as a critical HPLC reference standard for quantifying related impurities in cholic acid derivatives during pharmaceutical synthesis.
