Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Fluoro-4-methoxyphenylmagnesium bromide, 0.50 M in 2-MeTHF.
3-Fluoro-4-methoxyphenylmagnesium bromide, 0.50 M in 2-MeTHF (CAS 112780-67-3) is a high-purity analytical reference standard with the molecular formula C7H6FOBrMg and a molecular weight of 229.33 g/mol.
Owing to a salt form, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 3-Fluoro-4-methoxyphenylmagnesium bromide, 0.50 M in 2-MeTHF is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 229.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
