Chemical Structure
Description
The occurrence of (3-Amino-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinolin-2-yl)(4-fluorophenyl)methanone is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (3-Amino-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinolin-2-yl)(4-fluorophenyl)methanone (CAS 445269-22-7), a certified reference material (molecular formula C20H19FN2OS, MW 354.44 g/mol) for analytical method development and quality control.
(3-Amino-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinolin-2-yl)(4-fluorophenyl)methanone (C20H19FN2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Amino-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinolin-2-yl)(4-fluorophenyl)methanone 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.
