Chemical Structure
Description
The occurrence of tert-Butyl(2,3-difluoro-4-nitrophenoxy)dimethylsilane is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl(2,3-difluoro-4-nitrophenoxy)dimethylsilane (CAS 1881320-91-7) is a high-purity analytical reference standard with the molecular formula C12H17F2NO3Si and a molecular weight of 289.35 g/mol.
tert-Butyl(2,3-difluoro-4-nitrophenoxy)dimethylsilane (C12H17F2NO3Si) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
