Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 265.82 g/mol gives 2-Fluoro-4-iodophenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Fluoro-4-iodophenylboronic acid (CAS 374790-98-4) is a high-purity analytical reference standard with the molecular formula C6H5BFIO2 and a molecular weight of 265.82 g/mol.
Structurally, 2-Fluoro-4-iodophenylboronic acid (C6H5BFIO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 265.82 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
