Chemical Structure
Description
The occurrence of 4,5-Dibromo-2-iodotoluene is closely related to bromine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,5-Dibromo-2-iodotoluene (CAS 1160574-02-6), molecular formula C7H5Br2I and molecular weight 375.83 g/mol, is a CATO reference standard with documented purity and traceability.
4,5-Dibromo-2-iodotoluene (C7H5Br2I) contains 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4,5-Dibromo-2-iodotoluene 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.
