5-Hydroxy Imidacloprid

5-Hydroxy Imidacloprid is a structurally modified analog of Imidacloprid, featuring a hydroxyl substitution at the 5-position of the imidazole ring, replacing the nitro group characteristic of the parent compound. This substitution introduces a polar hydroxyl moiety, altering its electronic properties and reactivity. The molecule retains a chloropyridine moiety and a 1-methyl-2-oxo-4H-imidazol-4-ylidene bridge, maintaining core scaffold interactions. As an API impurity, it arises via oxidative degradation pathways, serving as a critical reference standard for HPLC-based quantification of degradation products in pharmaceutical stability studies.
