Quality Control

Our 2-(4'-Maleimidylanilino)Naphthalene-6-Sulfonic Acid Sodium Salt is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your research and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
