Chemical Structure
Description
The occurrence of (3-Bromo-4-fluorophenoxy)(tert-butyl)dimethylsilane is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3-Bromo-4-fluorophenoxy)(tert-butyl)dimethylsilane (CAS 1037088-98-4), molecular formula C12H18BrFOSi and molecular weight 305.26 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H18BrFOSi, (3-Bromo-4-fluorophenoxy)(tert-butyl)dimethylsilane contains a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 305.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
