Quality Control

Every batch of 9H-Fluorene-2-Carbonyl Chloride,9-Oxo is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC for purity and identity confirmation, is performed. A Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment to guarantee traceability and product integrity.

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 tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from strong acids and organic solvents.
