Quality Control

Our 2-Hydroxypropane-2-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 the high standards required for industrial and fine chemical applications. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment to guarantee traceability and consistency.

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, and open flame. Due to its nature as a strong acid/organic solvent, it should be stored separately from bases, oxidizing agents, and incompatible materials. Use appropriate corrosion-resistant storage containers.
