Quality Control

Our β-D-Glucopyranoside, 4-[(1E)-2-(3,5-Dihydroxyphenyl)Ethenyl]-2-Hydroxyphenyl is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing batch-specific results are available upon request. We can support development projects requiring compliance with ISO and GMP guidelines.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, the container must be kept tightly sealed in a dry environment and protected from light exposure to maintain stability and purity.
