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 2-Bromo-4-cyclopropoxy-1-isopropylbenzene (CAS 1243284-62-9), a certified reference material (molecular formula C12H15BrO, MW 255.15 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-Bromo-4-cyclopropoxy-1-isopropylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 255.15 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.
