Description
The occurrence of ((6,6,8,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,2,4,4-tetrayl)tetrakis(ethane-2,1-diyl))tetrakis(diphenylphosphine) is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
((6,6,8,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,2,4,4-tetrayl)tetrakis(ethane-2,1-diyl))tetrakis(diphenylphosphine) (CAS 124998-64-7), molecular formula C60H68O4P4Si4 and molecular weight 1089.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, ((6,6,8,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,2,4,4-tetrayl)tetrakis(ethane-2,1-diyl))tetrakis(diphenylphosphine) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1089.42 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.
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), ((6,6,8,8-Tetramethyl-1,3,5,7,2,4,6,8-tetraoxatetrasilocane-2,2,4,4-tetrayl)tetrakis(ethane-2,1-diyl))tetrakis(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.
