Chemical Structure
Description
3-Bromo-5-chloro-4-iodophenol (CAS 2091672-94-3) is a high-purity analytical reference standard with the molecular formula C6H3BrClIO and a molecular weight of 333.35 g/mol.
3-Bromo-5-chloro-4-iodophenol (C6H3BrClIO) contains a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Bromo-5-chloro-4-iodophenol 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.
