Description
Compared with other compounds in its class, the molecular weight of 269.27 g/mol gives 5-Fluoro-1-phenethylindoline-2,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Fluoro-1-phenethylindoline-2,3-dione (CAS 879479-47-7), molecular formula C16H12FNO2 and molecular weight 269.27 g/mol, is a CATO reference standard with documented purity and traceability.
5-Fluoro-1-phenethylindoline-2,3-dione (C16H12FNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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.
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.
CATO manufactures 5-Fluoro-1-phenethylindoline-2,3-dione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
