Quality Control

Our -Cacid CAS NO 444344-91-6 is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including purity assay and impurity profiling, to ensure it meets the stringent requirements of our global B2B clients. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with each shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is 15-25°C. Due to its nature as a strong acid/organic solvent, ensure containers are kept upright and sealed to prevent moisture absorption and contamination.
