Quality Control

Our 3-Furancarboxylic Acid, Tetrahydro-4-Keto-2-Phenylimino-, Ethyl Ester (1Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods (NMR, IR), to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, the container should be opaque or stored in dark conditions.
