4-Bromo-2-fluoro-3-iodobenzoic acid CAS 1809157-98-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-fluoro-3-iodobenzoic acid.

4-Bromo-2-fluoro-3-iodobenzoic acid (CAS 1809157-98-9), molecular formula C7H3BrFIO2 and molecular weight 344.90 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H3BrFIO2, 4-Bromo-2-fluoro-3-iodobenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 344.90 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 4-Bromo-2-fluoro-3-iodobenzoic acid 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.
