Chemical Structure

Ethyl 4-fluoro-2-(trifluoromethyl)benzoate CAS 167758-89-6 chemical structure

Description

The occurrence of Ethyl 4-fluoro-2-(trifluoromethyl)benzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 4-fluoro-2-(trifluoromethyl)benzoate (CAS 167758-89-6), molecular formula C10H8F4O2 and molecular weight 236.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Ethyl 4-fluoro-2-(trifluoromethyl)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
