Quality Control

Our 2-Hydroxyethyl-4-Phosphonobenzoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials.
