Quality Control

Every batch of our Benzenesulfonyl Chloride, 4-Fluoro-2-Nitro- (9Ci) is produced and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, GC, NMR, and IR spectroscopy to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specification parameters is provided with each shipment, ensuring full traceability and compliance with 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 tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
