Quality Control

Our 3-(Toluene-4-Sulfonylamino)-Propionic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and loss on drying, to ensure it meets precise specifications for research and industrial use. Certificates of Analysis (COA) documenting all test results are available upon request, providing full traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
