Quality Control

Our 2-Chloro-4-Methoxybenzene-1,3-Diol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing traceability and consistent quality for your critical applications.

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 after opening to prevent degradation from atmospheric moisture.
