3-Amino-N-(2,4-difluorophenyl)-4-(trifluoromethyl)-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide (CAS 626227-71-2), molecular formula C19H14F5N3OS and molecular weight 427.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Amino-N-(2,4-difluorophenyl)-4-(trifluoromethyl)-5H,6H,7H,8H-thieno[2,3-b]quinoline-2-carboxamide (C19H14F5N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 427.39 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
