Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((Dichloro(phenyl)silyl)oxy)-2,4,4,6,6-pentaphenyl-1,3,5,2,4,6-trioxatrisilinane (CAS 247180-40-1) is a high-purity analytical reference standard with the molecular formula C36H30Cl2O4Si4 and a molecular weight of 709.87 g/mol.
The molecular framework of 2-((Dichloro(phenyl)silyl)oxy)-2,4,4,6,6-pentaphenyl-1,3,5,2,4,6-trioxatrisilinane (C36H30Cl2O4Si4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-((Dichloro(phenyl)silyl)oxy)-2,4,4,6,6-pentaphenyl-1,3,5,2,4,6-trioxatrisilinane 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.
