Quality Control

Our 2-(Dicyclohexylphosphino)Benzenesulfonic Acid is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (¹H, ³¹P), HPLC for purity assessment, and Karl Fischer titration for moisture content, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

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 minimize oxidation and moisture absorption. The container should be kept in a well-ventilated area. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation.
