Quality Control

Our Pentachlorophenoxyacetic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including identity confirmation by FT-IR and NMR, purity determination by HPLC, and impurity profiling to ensure it meets the high standards required for research and synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting all critical quality attributes.

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 each use to prevent degradation from atmospheric moisture.
