Quality Control

Our 1,4-Bis(Di-I-Propylphosphino)Butane is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity and assay, with comprehensive impurity profiling. Certificates of Analysis (COA) detailing all test results are provided and available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, containers should be kept sealed and only opened in an inert environment.
