Quality Control

Our Bis(Hydroxymethyl)Methylphenylphosphonium Iodide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and titration for assay determination, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all test results are provided with each shipment to guarantee traceability, consistency, and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
