(S)-SIPHOS-PE, 25 mg

(S)-SIPHOS-PE is a defined organophosphorus research chemical with CAS number 500997-70-6 and empirical formula C₃₃H₃₂NO₂P. Its molar mass is 505,59 g/mol, supporting accurate stoichiometric planning in small-scale synthetic and catalytic work. This listing supplies, suited to method development, ligand screening, and reference use where only limited quantities are required. The compound is available from manufacturer Carl ROTH within its biochemicals portfolio and is intended for controlled laboratory handling. Clear identity data—CAS registry number, molecular formula, and molar mass—simplify inventory registration, batch documentation, and protocol transfer between research groups. The compact unit quantity helps laboratories evaluate performance or build focused compound sets without carrying large stocks. Typical contexts include asymmetric synthesis studies, catalyst ligand exploration, and fine-chemical research workflows that demand a well-specified phosphorus-containing structure. Consistent labelling of formula and mass supports reproducible weighing and reporting across discovery and process-chemistry environments.
