Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 211.62 g/mol gives 3-(Chloromethyl)-5-(2-fluorophenyl)isoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-(Chloromethyl)-5-(2-fluorophenyl)isoxazole (CAS 753479-56-0), a certified reference material (molecular formula C10H7ClFNO, MW 211.62 g/mol) for analytical method development and quality control.
3-(Chloromethyl)-5-(2-fluorophenyl)isoxazole (C10H7ClFNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
