Chemical Structure

4-Fluorobenzyl magnesium chloride CAS 1643-73-8 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-Fluorobenzyl magnesium chloride (CAS 1643-73-8) is a high-purity analytical reference standard with the molecular formula C7H12ClFMg and a molecular weight of 174.93 g/mol.

4-Fluorobenzyl magnesium chloride (C7H12ClFMg) contains a salt form, fluorine/chlorine 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.
