Quality Control

We maintain a strict quality management system to ensure batch-to-batch consistency and high purity. Our production of Spiro[1H-Indene-1,3-Pyrrolidine]-4,5-Diol, 2,3-Dihydro- adheres to current Good Manufacturing Practice (GMP) principles where applicable. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles, available upon request. Our quality commitment ensures the material meets the exacting standards required for advanced synthetic applications.

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 sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent moisture absorption and potential degradation. Recommended storage temperature is 2-8°C for extended stability.
