Quality Control

Every batch of Dipotassium 2,6-Naphthalenedisulfonate is manufactured under a strict quality management system. Our products undergo rigorous quality testing, including HPLC and titration methods, to ensure compliance with industry standards and customer specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

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 tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling.
