Chemical Structure
Description
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.
4-((4-Iodobenzyl)oxy)benzaldehyde (CAS 443289-91-6), molecular formula C14H11IO2 and molecular weight 338.14 g/mol, is a CATO reference standard with documented purity and traceability.
4-((4-Iodobenzyl)oxy)benzaldehyde (C14H11IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. 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.
