Quality Control

Our production of 5-Pyrrolidinedione, 1, 1'-(methylenedi-4,1-phenylene)bis[3-[(3-hydroxyphenyl)amino]- adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and precise moisture content analysis. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This compound is light-sensitive and may be hygroscopic; therefore, containers should be kept sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent oxidation and moisture uptake.
