Chemical Structure
Description
3-Fluoro-4-(methylsulfonyl)aniline hydrochloride (CAS 1197233-67-2), molecular formula C7H8FNO2SHCl and molecular weight 225.66 g/mol, is a CATO reference standard with documented purity and traceability.
3-Fluoro-4-(methylsulfonyl)aniline hydrochloride (C7H8FNO2SHCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3-Fluoro-4-(methylsulfonyl)aniline hydrochloride 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.
