Quality Control

Our 4-Carboxyphenylglyoxal is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere for long-term stability. Keep away from strong oxidizing agents, strong bases, and heat sources.
