Chemical Structure
Description
The occurrence of 4-FLUORO-3-(TRIFLUOROMETHYL)BENZOYL CHLORIDE 4-Fluoro-3-(trifluoromethyl)benzoylchloride 67515-56-4 ALPHA,ALPHA,ALPHA,4-TETRAFLUORO-M-TOLUOYL CHLORIDE AS00071 is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-FLUORO-3-(TRIFLUOROMETHYL)BENZOYL CHLORIDE 4-Fluoro-3-(trifluoromethyl)benzoylchloride 67515-56-4 ALPHA,ALPHA,ALPHA,4-TETRAFLUORO-M-TOLUOYL CHLORIDE AS00071 (CAS 67515-56-4), molecular formula C8H3ClF4O and molecular weight 226.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-FLUORO-3-(TRIFLUOROMETHYL)BENZOYL CHLORIDE 4-Fluoro-3-(trifluoromethyl)benzoylchloride 67515-56-4 ALPHA,ALPHA,ALPHA,4-TETRAFLUORO-M-TOLUOYL CHLORIDE AS00071 (C8H3ClF4O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
