Chemical Structure
Description
Tris(3-fluorophenyl)(phenyl)silane (CAS 2804-88-8) is a high-purity analytical reference standard with the molecular formula C24H17F3Si and a molecular weight of 390.47 g/mol.
Structurally, Tris(3-fluorophenyl)(phenyl)silane (C24H17F3Si) contains fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 390.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Tris(3-fluorophenyl)(phenyl)silane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
