Quality Control

Every batch of 3-[[5-Hydroxy-2-[(4-Hydroxyphenyl)Sulphonyl]Phenyl]Methyl]Naphthalene-2-Sulphonic Acid is produced and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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.
