Chemical Structure
Description
1-Bromo-3-chloro-2-iodo-5-methylbenzene (CAS 1774897-04-9), molecular formula C7H5BrClI and molecular weight 331.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-3-chloro-2-iodo-5-methylbenzene (C7H5BrClI) contains chlorine/bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 331.38 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures 1-Bromo-3-chloro-2-iodo-5-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.
