Quality Control

Our Lipoic Acid is manufactured under strict quality management systems. We offer grades compliant with major pharmacopoeial standards, including USP and EP, ensuring suitability for demanding pharmaceutical and nutraceutical applications. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. Certificates of compliance for REACH and other relevant regulatory frameworks are available.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider packaging under an inert gas such as nitrogen or argon to maintain optimal stability and purity.
