Quality Control

Our Phosphonium Choline is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with REACH and other relevant global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere to prevent degradation. Keep away from strong oxidizing agents.
