Quality Control

Our T-Butyldicyclohexylphosphine is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR and HPLC analysis, to verify identity and assay. Certificates of Analysis (COA) documenting all critical quality attributes are 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) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Due to its moisture-sensitive and easily oxidized nature, containers should be opened and handled in a controlled, dry environment.
