Chemical Structure
Description
The occurrence of Dodecyltris(3-fluorophenyl)silane is closely related to fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dodecyltris(3-fluorophenyl)silane (CAS 2128-45-2), molecular formula C30H37F3Si and molecular weight 482.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, a polycyclic aromatic system, Dodecyltris(3-fluorophenyl)silane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 482.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
