Quality Control

Our Dilithium Mercaptosuccinate is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and quantification of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable, supporting its use in regulated development environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and oxidation. Keep away from incompatible materials such as strong acids and oxidizing agents.
