Chemical Structure
Description
Based on its molecular formula C9H9IO4, 2-Iodo-3,4-dimethoxybenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 308.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
2-Iodo-3,4-dimethoxybenzoic acid (CAS 6335-18-8), molecular formula C9H9IO4 and molecular weight 308.07 g/mol, is a CATO reference standard with documented purity and traceability.
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.
