Quality Control

Our 4-Chloro-2-Nitrophenyl Isocyanate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat, sparks, open flames, and strong bases.
