Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 328.90 g/mol gives 3-Bromo-2-fluoro-5-iodobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-2-fluoro-5-iodobenzaldehyde (CAS 2091143-73-4), molecular formula C7H3BrFIO and molecular weight 328.90 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Bromo-2-fluoro-5-iodobenzaldehyde (C7H3BrFIO) contains a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 328.90 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Bromo-2-fluoro-5-iodobenzaldehyde 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.
