Quality Control

Our 4-Nitrophenyl Chloroacetate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, confirming compliance with customer specifications and industry standards for fine chemicals.

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 and under dry conditions to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
