Quality Control

Our 2-Chloro-4-Nitrophenyl Isocyanate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity, and is supplied with a detailed Certificate of Analysis (COA) to verify compliance with customer specifications. We adhere to cGMP principles where applicable to support its use in regulated synthesis pathways.

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 moisture-sensitive (hygroscopic) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
