SSS Ezetimibe is a fluorinated analog of Ezetimibe, featuring a tetrahydro-naphthalene core linked to a 4-(4-fluorophenoxy)benzoyl group and a trifluoromethyl-substituted aliphatic chain. This impurity arises from a fluorinated intermediate in the synthetic pathway, retaining the parent drug's phenoxyphenyl and carboxylic acid moieties. It serves as an HPLC reference standard for quantifying process-related impurities in Ezetimibe API.
