Compared with other compounds in its class, the molecular weight of 375.35 g/mol gives 1-(((2S,4S,5R)-4-(2,4-Difluorophenyl)-5-(2-tosylethyl)-1,3-dioxolan-2-yl)methyl)-1H-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(((2S,4S,5R)-4-(2,4-Difluorophenyl)-5-(2-tosylethyl)-1,3-dioxolan-2-yl)methyl)-1H-1,2,4-triazole (CAS 171764-49-1), molecular formula C14H15F2N3O5S and molecular weight 375.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(((2S,4S,5R)-4-(2,4-Difluorophenyl)-5-(2-tosylethyl)-1,3-dioxolan-2-yl)methyl)-1H-1,2,4-triazole (C14H15F2N3O5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
