Esomeprazole Impurity 22 is a critical reference standard for quality control in pharmaceutical manufacturing, defined as a specific degradant of the proton pump inhibitor esomeprazole. Synthesized via precise oxidative coupling or hydrolysis pathways during API production, its identity is verified by molecular formula C17H18N4O3S and CAS No. 159620-45-2.
This substance must be stored in sealed containers at -20°C away from light to prevent degradation. Handling requires appropriate PPE including gloves and goggles due to potential irritancy, ensuring strict adherence to safety data sheet protocols.
