Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1389.96 g/mol gives PSS-Octakis[2-(Chlorodimethylsilyl)ethyl] substituted distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
PSS-Octakis[2-(Chlorodimethylsilyl)ethyl] substituted (CAS 243146-51-2) is a high-purity analytical reference standard with the molecular formula C32H80Cl8O12Si16 and a molecular weight of 1389.96 g/mol.
PSS-Octakis[2-(Chlorodimethylsilyl)ethyl] substituted (C32H80Cl8O12Si16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), PSS-Octakis[2-(Chlorodimethylsilyl)ethyl] substituted 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.
