Quality Control

Our production of Potassium 4-(11-Methacrylamidoundecanamido)Benzenesulfonate adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure consistency and reliability for your critical applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key specifications such as assay, impurity profile, and moisture content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry conditions to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
