Quality Control

Our (+)-Methylphenylpropylphosphine is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity (enantiomeric excess) determination by chiral HPLC or GC, identity confirmation by NMR and IR spectroscopy, and assay by titration. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Due to its sensitivity to oxidation, containers should be purged with inert gas after each opening.
