Pantoprazole sodium

Pantoprazole sodium (CAS 138786-67-1), also marketed as Protonix, is a proton pump inhibitor active pharmaceutical ingredient used in the manufacture of prescription gastrointestinal medications.

Where is Pantoprazole sodium used?

• Oral tablets and intravenous formulations: active component
• Acid-related gastrointestinal conditions: core procurement target for finished dosage form manufacturers
• Enteric-coated tablet production: starting material for generic drug producers
• Sterile injectables: high-purity grades for parenteral formulation standards
• Pharmaceutical reference standard suppliers and QC laboratories source it for analytical and method validation purposes.

Good to know: The anhydrous form is the primary commercially traded specification, distinct from the sesquihydrate salt used in some finished formulations. Acid-resistant coating is critical to bioavailability in these applications.

Commercial specifications

• API-grade specifications conforming to USP, BP, and Ph. Eur. pharmacopoeial standards
• Packaging from small quantities for laboratory use to multi-kilogram lots for manufacturing
