Chemical Structure
Description
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.
2-Methyl-5-(pentafluoro-λ6-sulfanyl)aniline (CAS 623943-52-2), molecular formula C7H8F5NS and molecular weight 233.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Methyl-5-(pentafluoro-λ6-sulfanyl)aniline (C7H8F5NS) 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.
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.
