Quality Control

Our 5-(4-Hydroxyphenyl)Benzene-1,3-Dicarboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are provided with every shipment. We can supply material compliant with various pharmacopeial standards upon request.

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). The compound may be light-sensitive and hygroscopic; therefore, containers should be kept sealed under an inert atmosphere when not in use to prevent moisture absorption and potential degradation. Keep away from strong oxidizing agents.
