Quality Control

Our Naphthalene-1-Sulfonic Acid Hydrate, 98% is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the declared specification for identity, purity, and impurity profile. Certificates of Analysis (COA) documenting these results are provided as standard, ensuring traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
