Quality Control

Our Dodecane-1-Sulphonic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee traceability and compliance.

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. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed to prevent moisture absorption and degradation. Recommended storage temperature is 15-25°C.
