Quality Control

Our Methylene Bis-(Chlorosulfate) (Mbcs) is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including assay and impurity profile determination by techniques such as HPLC and NMR, to ensure consistency and high purity suitable for synthetic applications. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 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 decomposition. Keep away from strong bases and incompatible materials.
