Pantoprazole Impurity 3 and 4 are degradation byproducts of the proton pump inhibitor pantoprazole. Impurity 3 (CAS 158207-69-5) features a sulfide structure, while Impurity 4 (CAS 158207-70-8) is an oxidized sulfone analog. Both are critical for validating pharmaceutical synthesis routes.
Store under inert atmosphere at -20°C to prevent oxidation. Personnel must wear appropriate PPE due to potential irritancy. Strictly limit clinical exposure as these compounds lack therapeutic efficacy and may possess unknown toxicological profiles.
