Quality Control

Our 4-Nitrophenyl 3-Ethyl-4-Methyl-2-Oxo-2,5-Dihydro-1H-Pyrrole-1-Carboxylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via NMR and IR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize headspace in opened containers.
