Quality Control

Our Tetrapropylenebenzenesulphonic Acid is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, composition, and performance. We provide full traceability and detailed Certificates of Analysis (COA) with key parameters including assay, sulfonic acid content, and free oil content, meeting the specifications required for industrial and chemical synthesis applications.

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 strong acid/organic solvent nature, containers must be kept tightly sealed to prevent moisture absorption and maintain product integrity. Recommended storage temperature: 15-25°C.
