Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.64 g/mol gives Ethyl 4-chloro-3-fluoro-2-methoxybenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 4-chloro-3-fluoro-2-methoxybenzoate (CAS 2113520-17-3), a certified reference material (molecular formula C10H10ClFO3, MW 232.64 g/mol) for analytical method development and quality control.
Ethyl 4-chloro-3-fluoro-2-methoxybenzoate (C10H10ClFO3) 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. 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.
