Quality Control

Our Potassium 1-Hydroxyethanesulphinate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets exacting standards for consistency and purity. Certificates of Analysis (COA) are provided with every shipment and are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
