Chemical Structure
Description
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.
CATO supplies (4S,5S)-1,3,4,5-tetraphenyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate (CAS 909252-47-7), a certified reference material (molecular formula C27H23N2BF4, MW 462.30 g/mol) for analytical method development and quality control.
Structurally, (4S,5S)-1,3,4,5-tetraphenyl-4,5-dihydro-1H-imidazol-3-ium tetrafluoroborate (C27H23N2BF4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 462.30 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
