Description
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.
1,5-Dibromo-2-iodo-4-methoxybenzene (CAS 1695962-39-0) is a high-purity analytical reference standard with the molecular formula C7H5Br2IO and a molecular weight of 391.83 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system, 1,5-Dibromo-2-iodo-4-methoxybenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 391.83 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.
CATO manufactures 1,5-Dibromo-2-iodo-4-methoxybenzene 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.
