5-Fluoro-2-methoxy-N-propyl-N-(thiophen-3-ylmethyl)benzenesulfonamide (CAS 1235311-21-3), molecular formula C15H18FNO3S2 and molecular weight 343.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Fluoro-2-methoxy-N-propyl-N-(thiophen-3-ylmethyl)benzenesulfonamide (C15H18FNO3S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
