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.
CATO supplies 4-Chloro-3-methylphenylmagnesium bromide, 0.50 M in THF (CAS 460747-53-9), a certified reference material (molecular formula C7H6ClBrMg, MW 229.78 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-3-methylphenylmagnesium bromide, 0.50 M in THF (C7H6ClBrMg) is characterized by a salt form, chlorine/bromine substitution, an aromatic ring system. 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.
