Chemical Structure
Description
3-Chloro-6-ethoxy-2-fluoro-5-(2-methyl-1,3-dioxolan-2-yl)benzaldehyde (C13H14ClFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Chloro-6-ethoxy-2-fluoro-5-(2-methyl-1,3-dioxolan-2-yl)benzaldehyde (CAS 1995889-49-0), molecular formula C13H14ClFO4 and molecular weight 288.70 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.
