Quality Control

Our α-Lipoic Acid is manufactured under strict quality management systems. We offer grades suitable for various applications, including those compliant with USP, EP, and FCC monographs. Every batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage or after opening, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve stability and potency. Keep away from strong oxidizing agents.
