Quality Control

Our Disodium Benzenedisulphonate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. We provide Certificates of Analysis (COA) with key parameters including assay, identity, and impurity profiles to guarantee batch-to-batch consistency and reliability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
