Quality Control

Our Cyclopentane, 1-Bromo-2-Isocyanato-, cis- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, assay, and impurity profiles. We adhere to cGMP guidelines where applicable to support our clients in regulated research and development environments.

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. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
