Quality Control

Our production of 1,3,6-Naphthalenetrisulfonic Acid derivative (CAS 79820-02-3) adheres to stringent quality management protocols to ensure batch-to-batch consistency and purity suitable for industrial synthesis. Each lot undergoes rigorous analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) detailing assay, impurity profile, and physical characteristics are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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, which can affect product stability and performance.
