Chemical Structure
Description
3-Ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoic acid (CAS 1706444-23-6) is a high-purity analytical reference standard with the molecular formula C17H17IO4 and a molecular weight of 412.22 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution, 3-Ethoxy-5-iodo-4-((4-methylbenzyl)oxy)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 412.22 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).
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.
