Mometason Furoate Impurity G is a chlorinated synthetic byproduct derived from the parent corticosteroid via oxidation of the 11ฮฒ-hydroxyl group to a keto functionality, coupled with C-16ฮฑ chlorination. Its structure retains the 9ฮฑ-fluoro and 17ฮฑ-propynyl moieties of mometasone furoate but features a 21-furoate ester linkage and a 16ฮฑ-chloro substitution, distinguishing it as a key degradation intermediate. This compound serves as an HPLC reference standard for quantifying process-related impurities in API batches.
