Introduction
Potassium phosphates are essential compounds widely used in pharmaceutical formulations, including intravenous solutions, nutritional supplements, and as buffering agents. The global demand hinges on the availability of high-quality raw materials supplied by a diverse array of manufacturers. This article methodically evaluates key suppliers of potassium phosphates in the pharmaceutical industry, focusing on their product portfolios, quality certifications, geographic presence, and strategic capabilities.
Overview of Potassium Phosphates in Pharmaceuticals
Potassium phosphates encompass several chemical forms, notably monopotassium phosphate (KH₂PO₄), dipotassium phosphate (K₂HPO₄), and tripotassium phosphate (K₃PO₄). These salts serve multiple functions:
- Buffering Agents: Maintain pH stability in formulations.
- Electrolyte Balance: Correct potassium levels in IV nutrition.
- Food and Supplementation: Nutritional electrolyte sources.
The pharmaceutical sector demands suppliers that adhere to strict quality standards such as cGMP compliance, ISO certifications, and USP, EP, or JP monographs. Ensuring raw material purity, consistent supply, and regulatory compliance is paramount.
