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.
7103-09-5 3-Butenylmagnesium bromide solution, 0.5 M in THF MFCD00209554 (CAS 7103-09-5) is a high-purity analytical reference standard with the molecular formula C4H7BrMg and a molecular weight of 159.31 g/mol.
The molecular framework of 7103-09-5 3-Butenylmagnesium bromide solution, 0.5 M in THF MFCD00209554 (C4H7BrMg) is characterized by a salt form, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
