Quality Control

Our 1H-Pyrrole-2,5-Dione,1-(4-Pentynyl)-(9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and development. We employ advanced analytical techniques including HPLC, GC, and NMR to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
