Quality Control

Our 4-(Hydroxymercury)Benzoic Acid Sodium Salt is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by titration and identification by spectroscopic methods, to ensure high purity and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as purity, heavy metal content, and loss on drying.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers. Keep away from incompatible materials.
