(5S)-5,6-Dihydro-5-(1-methylpropyl)-2-(2,3,4,5,6-pentafluorophenyl)-8H-1,2,4-triazolo[3,4-c][1,4]oxazinium tetrafluoroborate CAS 1449522-21-7

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.

CATO supplies (5S)-5,6-Dihydro-5-(1-methylpropyl)-2-(2,3,4,5,6-pentafluorophenyl)-8H-1,2,4-triazolo[3,4-c][1,4]oxazinium tetrafluoroborate (CAS 1449522-21-7), a certified reference material (molecular formula C15H15F5N3OBF3F, MW 435.10 g/mol) for analytical method development and quality control.

The molecular framework of (5S)-5,6-Dihydro-5-(1-methylpropyl)-2-(2,3,4,5,6-pentafluorophenyl)-8H-1,2,4-triazolo[3,4-c][1,4]oxazinium tetrafluoroborate (C15H15F5N3OBF3F) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

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.
