Quality Control

Our 4Mbc is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling, to meet the stringent requirements of our industrial and research partners. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents. Due to its light-sensitive nature and reactive chloride group, prolonged exposure to light or moisture should be avoided to maintain product integrity.
