Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.20 g/mol gives Ethyl 2-methyl-4-(trifluoromethyl)benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-methyl-4-(trifluoromethyl)benzoate (CAS 256232-92-5), molecular formula C11H11F3O2 and molecular weight 232.20 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 2-methyl-4-(trifluoromethyl)benzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Ethyl 2-methyl-4-(trifluoromethyl)benzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
