Chemical Structure
Description
CATO supplies 5-Fluoro-2-(trifluoromethyl)phenylacetonitrile (CAS 242812-09-5), a certified reference material (molecular formula C9H5F4N, MW 203.14 g/mol) for analytical method development and quality control.
Structurally, 5-Fluoro-2-(trifluoromethyl)phenylacetonitrile (C9H5F4N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 203.14 g/mol, it falls into the medium-molecular-weight range. 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.
