3-Amino-6-ethyl-N-(propan-2-yl)-4-(trifluoromethyl)-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide (CAS 939893-68-2) is a high-purity analytical reference standard with the molecular formula C18H22F3N3OS and a molecular weight of 385.45 g/mol.
The molecular framework of 3-Amino-6-ethyl-N-(propan-2-yl)-4-(trifluoromethyl)-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide (C18H22F3N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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.
