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.
2-(bromomethyl)-3-chloro-1-fluoro-4-methylbenzene 2-Chloro-6-fluoro-3-methylbenzyl bromide 261762-87-2 (CAS 261762-87-2) is a high-purity analytical reference standard with the molecular formula C8H7BrClF and a molecular weight of 237.50 g/mol.
Owing to fluorine/chlorine/bromine substitution, an aromatic ring system, 2-(bromomethyl)-3-chloro-1-fluoro-4-methylbenzene 2-Chloro-6-fluoro-3-methylbenzyl bromide 261762-87-2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.50 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.
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.
