Prop-2-yn-1-yl 3-chloro-4-((2,4-dichlorobenzyl)oxy)-5-ethoxybenzoate (CAS 1706446-03-8), molecular formula C19H15Cl3O4 and molecular weight 413.68 g/mol, is a CATO reference standard with documented purity and traceability.
Prop-2-yn-1-yl 3-chloro-4-((2,4-dichlorobenzyl)oxy)-5-ethoxybenzoate (C19H15Cl3O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
