Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Fluoro-5-(pentafluoro-λ6-sulfanyl)aniline.
CATO supplies 3-Fluoro-5-(pentafluoro-λ6-sulfanyl)aniline (CAS 1240256-99-8), a certified reference material (molecular formula C6H5F6NS, MW 237.17 g/mol) for analytical method development and quality control.
Structurally, 3-Fluoro-5-(pentafluoro-λ6-sulfanyl)aniline (C6H5F6NS) contains a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 237.17 g/mol, it falls into the medium-molecular-weight range. 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.
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.
