Quality Control

Our 7-(1,2,3,4-Tetrahydro-4,4,6-Trimethyl-2-Thioxopyrimidin-1-Yl)-1,3-Naphthalenedisulfonic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and physical characteristics are provided and 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 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. Keep away from strong acids and incompatible organic solvents.
