Chemical Structure

1,3-Dibromo-2-iodo-5-methoxybenzene CAS 201161-11-7 chemical structure

Description

The occurrence of 1,3-Dibromo-2-iodo-5-methoxybenzene is closely related to a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,3-Dibromo-2-iodo-5-methoxybenzene (CAS 201161-11-7), a certified reference material (molecular formula C7H5Br2IO, MW 391.83 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H5Br2IO, 1,3-Dibromo-2-iodo-5-methoxybenzene contains a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 391.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
