Desdiacetyl bisacodyl

Desdiacetyl bisacodyl is a synthetic derivative of bisacodyl, characterized by the removal of two acetyl groups from the 2-ethyl and 2′-methyl positions of the 1,1′-biphenyl-3,3′-dicarboxylic acid scaffold, resulting in free hydroxyl functionalities. This structural modification eliminates the ester moieties present in the parent compound, rendering it a key intermediate in oxidative degradation pathways. It serves as an HPLC reference standard for quantifying process-related impurities in bisacodyl formulations.
