Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine/iodine substitution, an aromatic ring system, 2-Amino-4-bromo-5-fluoro-3-iodobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
2-Amino-4-bromo-5-fluoro-3-iodobenzoic acid (CAS 2773311-18-3) is a high-purity analytical reference standard with the molecular formula C7H4BrFINO2 and a molecular weight of 359.92 g/mol.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
