Acetyl Brimonidine Impurity

Acetyl Brimonidine Impurity is a structurally modified derivative of Brimonidine, featuring an acetyl group substitution at the terminal amino functionality. This impurity retains the core imidazoline ring and brominated benzene moiety of the parent drug but incorporates an N-acetylated side chain, altering its physicochemical properties. The compound exhibits a substituted heterocyclic framework with a bromine atom at the 3-position of the phenyl ring and a tetrahydroimidazole core. It serves as a reference standard for HPLC-based quantification of acetylated impurities in Brimonidine-containing pharmaceuticals.
