Quality Control

Our Carbamic Acid, (4-Borono-3-Fluorophenyl)-, C-(Phenylmethyl) Ester (9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development applications. Each lot is analyzed using advanced techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation. Keep away from incompatible materials.
