Chemical Structure

1-Ethyl-2-(trifluoromethyl)benzene CAS 74423-01-1 chemical structure

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 1-Ethyl-2-(trifluoromethyl)benzene (CAS 74423-01-1), a certified reference material (molecular formula C9H9F3, MW 174.16 g/mol) for analytical method development and quality control.

Structurally, 1-Ethyl-2-(trifluoromethyl)benzene (C9H9F3) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 174.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
