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.
CATO supplies 2-Fluoro-3-trifluoromethylsulfanylpyrazine (CAS 1206524-61-9), a certified reference material (molecular formula C5H2F4N2S, MW 198.14 g/mol) for analytical method development and quality control.
The molecular framework of 2-Fluoro-3-trifluoromethylsulfanylpyrazine (C5H2F4N2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2-Fluoro-3-trifluoromethylsulfanylpyrazine 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.
