Quality Control

Our Tetrakis(4-Methylphenyl)Borane-Tetraphenylphosphine Complex is manufactured under controlled conditions to ensure high purity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C to maintain stability. Due to its hygroscopic and easily oxidized nature, the container should only be opened in a controlled, moisture-free environment.
