CATO supplies n-Ethyl-3-fluoro-2-methylaniline (CAS 75746-99-5), a certified reference material (molecular formula C9H12FN, MW 153.20 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H12FN, n-Ethyl-3-fluoro-2-methylaniline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 153.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), n-Ethyl-3-fluoro-2-methylaniline 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.
