Amlodipine Impurity 3 refers to 3‑Desethyl‑3‑(2‑phthalimidoethyl) Phthaloyl Amlodipine, a specific degradation or synthetic byproduct of amlodipine. It is not an active drug but is important in pharmaceutical quality control and analytical studies to monitor purity and ensure safety of amlodipine formulations. It retains the core dihydropyridine structure but includes chemical modifications like desethyl and phthaloyl groups.
