Biotage® PS-Triphenylphosphine
Supported phosphine reagent
Designed for Wittig and Mitsunobu reactions, chlorination of acids and alcohols, and the scavenging of alkyl halides.
Biotage® PS-Triphenylphosphine is a diphenylphosphinated polystyrene resin that is a solid-supported equivalent of triphenylphosphine.
Unlike the small molecule reagent, the triphenylphosphine oxide by-product of reaction stays 100% resin bound, meaning that removal of product from phosphine oxide can be accomplished by simple low tech filtration techniques.
With lot control, QA/QC documentation, SDS, ISO 9001/14001 registration, BSE/TSE statement and shelf-life statement, Biotage® PS-Triphenylphosphine also supports the audit trail.
