Chemical Structure
Description
3-Ethoxy-4-[(4-fluorobenzyl)oxy]-5-iodobenzaldehyde (CAS 346611-54-9) is a high-purity analytical reference standard with the molecular formula C16H14FIO3 and a molecular weight of 400.18 g/mol.
Based on its molecular formula C16H14FIO3, 3-Ethoxy-4-[(4-fluorobenzyl)oxy]-5-iodobenzaldehyde contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
