Quality Control

Our (2S,2'S,3S,3'S)-3,3'-Di-tert-Butyl-2,2'-Dimethyl-2,2',3,3'-Tetrahydro-4,4'-Bibenzo[D][1,3]Oxaphosphole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat and incompatible materials.
