Quality Control

Every batch of 3H-Oxireno[2,3]Cyclopenta[1,2-B]Pyrrole (9Ci) is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC-MS, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets your research 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
