Description
CATO supplies 2-Bromo-6-iodobenzaldehyde (CAS 1261497-91-9), a certified reference material (molecular formula C7H4BrIO, MW 310.91 g/mol) for analytical method development and quality control.
Structurally, 2-Bromo-6-iodobenzaldehyde (C7H4BrIO) contains a hydroxyl group, an ether linkage, 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 310.91 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-Bromo-6-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.
