Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 248.02 g/mol gives 2-Hydroxy-3-iodobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Hydroxy-3-iodobenzaldehyde (CAS 23602-64-4) is a high-purity analytical reference standard with the molecular formula C7H5IO2 and a molecular weight of 248.02 g/mol.
2-Hydroxy-3-iodobenzaldehyde (C7H5IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
