Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 480.04 g/mol gives 3,5-Diiodo Thyroaldehyde Methyl Ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3,5-Diiodo Thyroaldehyde Methyl Ether (CAS 69240-57-9), a certified reference material (molecular formula C14H10I2O3, MW 480.04 g/mol) for analytical method development and quality control.
3,5-Diiodo Thyroaldehyde Methyl Ether (C14H10I2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
