Chemical Structure
Description
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.
(4-Fluorobutyl)magnesium bromide, 0.50 M in THF (CAS 169250-13-9) is a high-purity analytical reference standard with the molecular formula BrC4H8FMg and a molecular weight of 179.31 g/mol.
(4-Fluorobutyl)magnesium bromide, 0.50 M in THF (BrC4H8FMg) contains a salt form, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
