Quality Control

Our Cysteine Thiosulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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. For long-term stability, storage under an inert atmosphere (e.g., nitrogen or argon) is recommended to prevent oxidation.
