Chemical Structure
Description
1,2-Bis(di-2-pyridylphosphino)ethane (CAS 106308-26-3), molecular formula C22H20N4P2 and molecular weight 402.37 g/mol, is a CATO reference standard with documented purity and traceability.
1,2-Bis(di-2-pyridylphosphino)ethane (C22H20N4P2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,2-Bis(di-2-pyridylphosphino)ethane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
