Chemical Structure

N,n-bis(trimethylsilyl)-2,3,4,5,6-pentafluoroaniline CAS 23188-59-2 chemical structure

Description

Structurally, N,n-bis(trimethylsilyl)-2,3,4,5,6-pentafluoroaniline (C12H18F5NSi2) contains a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 327.44 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

N,n-bis(trimethylsilyl)-2,3,4,5,6-pentafluoroaniline (CAS 23188-59-2), molecular formula C12H18F5NSi2 and molecular weight 327.44 g/mol, is a CATO reference standard with documented purity and traceability.

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.
