Quality Control

Our Di-tert-Butylphosphine is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and titration to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored and handled under an inert atmosphere (argon or nitrogen). Recommended storage temperature is 2-8°C in a cool, dry, well-ventilated area, away from heat and ignition sources.
