Chemical Structure
Description
1-Fluoro-2-(sulfinylamino)benzene (CAS 74653-64-8) is a high-purity analytical reference standard with the molecular formula C6H4FNOS and a molecular weight of 157.17 g/mol.
The molecular framework of 1-Fluoro-2-(sulfinylamino)benzene (C6H4FNOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Fluoro-2-(sulfinylamino)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
