Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 157.21 g/mol gives 3-Fluoro-2-(methylthio)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Fluoro-2-(methylthio)aniline (CAS 305811-07-8), molecular formula C7H8FNS and molecular weight 157.21 g/mol, is a CATO reference standard with documented purity and traceability.
3-Fluoro-2-(methylthio)aniline (C7H8FNS) contains a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures 3-Fluoro-2-(methylthio)aniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
