Chemical Structure
Description
As a certified reference material (CRM), 4-Bromo-3-iodobenzoyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-Bromo-3-iodobenzoyl chloride (CAS 42860-24-2), a certified reference material (molecular formula C7H3BrClIO, MW 345.36 g/mol) for analytical method development and quality control.
The molecular framework of 4-Bromo-3-iodobenzoyl chloride (C7H3BrClIO) is characterized by a hydroxyl group, an ether linkage, chlorine/bromine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
