Quality Control

Our Cystamine Sulfate Hydrate, 98% is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR), and tests for related substances and moisture content, to ensure it meets the declared 98% minimum purity specification. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
