4-tert-Butyl-2,6-dimethylphenylmagnesium bromide 0.5 M in Tetrahydrofuran (CAS 400656-18-0), molecular formula C12H17BrMg and molecular weight 265.47 g/mol, is a CATO reference standard with documented purity and traceability.
4-tert-Butyl-2,6-dimethylphenylmagnesium bromide 0.5 M in Tetrahydrofuran (C12H17BrMg) contains a salt form, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
