Quality Control

Our Cyclopentane, 1-Bromo-2-Isocyanato-, trans- (9Ci) is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. We employ advanced analytical techniques including HPLC, GC, and NMR to verify identity, purity, and isomeric composition. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance and regulatory documentation.

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 a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, and open flame.
