Quality Control

Our Methyl Viologen Dichloride Hydrate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by FT-IR, to ensure it meets the specified 98% minimum purity standard. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and away from direct light exposure to maintain stability and purity.
