Description

Compared with other compounds in its class, the molecular weight of 340.94 g/mol gives 5-Bromo-3-iodo-2-methoxybenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-3-iodo-2-methoxybenzaldehyde (CAS 832674-07-4), molecular formula C8H6BrIO2 and molecular weight 340.94 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-3-iodo-2-methoxybenzaldehyde (C8H6BrIO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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.

CATO manufactures 5-Bromo-3-iodo-2-methoxybenzaldehyde 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.
