Quality Control

Our production of 3-[4-[9-[4-(2,5-Dioxopyrrolidin-3-Yl)Phenoxy]Nonoxy]Phenyl]Pyrrolidine -2,5-Dione adheres to stringent quality protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure compliance with exacting R&D and pharmaceutical intermediate standards. Certificates of Analysis (COA) detailing batch-specific results 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 (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and performance. For long-term storage, consider using desiccants.
