Chemical Structure
Description
Owing to organophosphorus functionality, a polycyclic aromatic system, Ethane-1,1-diylbis(diphenylphosphane) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies Ethane-1,1-diylbis(diphenylphosphane) (CAS 28240-60-0), a certified reference material (molecular formula C26H24P2, MW 398.42 g/mol) for analytical method development and quality control.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Ethane-1,1-diylbis(diphenylphosphane) 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.
