Chemical Structure
Description
The molecular framework of 3-Fluoro-5-(pentafluoro-λ6-sulfanyl)benzonitrile (C7H3F6NS) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. 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.
CATO supplies 3-Fluoro-5-(pentafluoro-λ6-sulfanyl)benzonitrile (CAS 1373920-62-7), a certified reference material (molecular formula C7H3F6NS, MW 247.16 g/mol) for analytical method development and quality control.
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.
