Description
CATO manufactures 4-Bromo-2-iodo-1-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-Bromo-2-iodo-1-methylbenzene (CAS 260558-15-4) is a high-purity analytical reference standard with the molecular formula C7H6BrI and a molecular weight of 296.93 g/mol.
Based on its molecular formula C7H6BrI, 4-Bromo-2-iodo-1-methylbenzene contains bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 296.93 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
