Quality Control

Our 3-(2,3-Dihydroxypropyloxy)-1-Propanesulfonic Acid Sodium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial use. A comprehensive Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and performance.
