Description
Compared with other compounds in its class, the molecular weight of 299.30 g/mol gives 3-(3-Fluorophenyl)-5-(2-methyl-1,3-dioxolan-2-yl)benzo[c]isoxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(3-Fluorophenyl)-5-(2-methyl-1,3-dioxolan-2-yl)benzo[c]isoxazole (CAS 383147-30-6) is a high-purity analytical reference standard with the molecular formula C17H14FNO3 and a molecular weight of 299.30 g/mol.
Structurally, 3-(3-Fluorophenyl)-5-(2-methyl-1,3-dioxolan-2-yl)benzo[c]isoxazole (C17H14FNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 299.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
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.
