Quality Control

Our n-(4-Methylumbelliferyl)-Maleinimid is manufactured under strict quality control protocols to ensure high purity and batch-to-batch consistency suitable for research and diagnostic applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for identity confirmation. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
