Quality Control

Our 9-(2-Carboxylato-4-Carboxyphenyl)-3,6-Bis(Diethylamino)Xanthylium is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive applications in dye and reagent synthesis. Certificates of Analysis (COA) detailing lot-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
