Quality Control

Our 3A,4,5,7A-Tetrahydro-1H-Isoindole-1,3(2H)-Dione is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We support custom synthesis and can tailor purity grades to meet specific research or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
