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.
4-Fluoro-2-(trifluoromethyl)aniline hydrochloride (CAS 139291-82-0), molecular formula C7H5F4NHCl and molecular weight 215.57 g/mol, is a CATO reference standard with documented purity and traceability.
4-Fluoro-2-(trifluoromethyl)aniline hydrochloride (C7H5F4NHCl) contains a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4-Fluoro-2-(trifluoromethyl)aniline hydrochloride 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.
