Description

Compared with other compounds in its class, the molecular weight of 289.73 g/mol gives 5-(5-Chloro-2-fluorophenyl)-3-methyl-3-phenyl-2,3-dihydroisoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(5-Chloro-2-fluorophenyl)-3-methyl-3-phenyl-2,3-dihydroisoxazole (CAS 877862-70-9), molecular formula C16H13ClFNO and molecular weight 289.73 g/mol, is a CATO reference standard with documented purity and traceability.

5-(5-Chloro-2-fluorophenyl)-3-methyl-3-phenyl-2,3-dihydroisoxazole (C16H13ClFNO) 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 5-(5-Chloro-2-fluorophenyl)-3-methyl-3-phenyl-2,3-dihydroisoxazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
