Quality Control

Our Dibutylchlorophosphine is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration or GC, identity confirmation by FT-IR or NMR, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and bases.
