Quality Control

Our Tetrabutylphosphonium Malonate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, Karl Fischer titration for water content, and spectroscopic identification (IR, NMR). A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications.

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). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
