Quality Control

Every batch of 4-(Benzyloxy)Naphthalene-1-Sulfonic Acid is produced and tested under a strict quality management system. We ensure high purity and consistent performance through comprehensive analytical protocols, including HPLC, NMR, and mass spectrometry. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and conformity to agreed specifications.

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 sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
