Quality Control

Our 3-(β-D-Galactopyranosyloxy)-5,7-Dihydroxy-2-(4-Hydroxy-3-Methoxyphenyl)-1-Benzopyrylium Chloride is produced and handled under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, UV-Vis), to ensure it meets exacting standards for research and development use. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting critical quality attributes. We support compliance needs for research applications in regulated environments.

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 compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
