[2,7-Di(tert-butyl)-9,9-dimethylxanthene-4,5-diyl]bis(diphenylphosphine) CAS 221462-97-1

Description

As a certified reference material (CRM), [2,7-Di(tert-butyl)-9,9-dimethylxanthene-4,5-diyl]bis(diphenylphosphine) 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.

[2,7-Di(tert-butyl)-9,9-dimethylxanthene-4,5-diyl]bis(diphenylphosphine) (CAS 221462-97-1) is a high-purity analytical reference standard with the molecular formula C47H48OP2 and a molecular weight of 690.83 g/mol.

[2,7-Di(tert-butyl)-9,9-dimethylxanthene-4,5-diyl]bis(diphenylphosphine) (C47H48OP2) contains organophosphorus functionality, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
