Quality Control

Our Isopimaric Acid Tms is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatographic purity assessment, to ensure it meets the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and assay results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
