Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 4-Ethoxy-3-iodobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-Ethoxy-3-iodobenzoic acid (CAS 82998-76-3) is a high-purity analytical reference standard with the molecular formula C9H9IO3 and a molecular weight of 292.07 g/mol.
