(2-Ethylhexyl)triphenylsilane (CAS 18765-65-6), molecular formula C26H32Si and molecular weight 372.62 g/mol, is a CATO reference standard with documented purity and traceability.
(2-Ethylhexyl)triphenylsilane (C26H32Si) contains 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (2-Ethylhexyl)triphenylsilane 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.
