Quality Control

Our Bis-(Triphenylphosphino)-Cuprous Borohydride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, elemental analysis, and titration methods, to confirm identity and assay. A detailed Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. This material is easily oxidized and moisture-sensitive; prolonged exposure to air or humidity must be avoided to maintain stability and efficacy.
