(3E)-3-[2-(4-Fluorophenyl)hydrazin-1-ylidene]-1-(propan-2-yl)-2,3-dihydro-1H-indol-2-one CAS 320422-07-9

Description

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.

(3E)-3-[2-(4-Fluorophenyl)hydrazin-1-ylidene]-1-(propan-2-yl)-2,3-dihydro-1H-indol-2-one (CAS 320422-07-9), molecular formula C17H16FN3O and molecular weight 297.33 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H16FN3O, (3E)-3-[2-(4-Fluorophenyl)hydrazin-1-ylidene]-1-(propan-2-yl)-2,3-dihydro-1H-indol-2-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
