The occurrence of 3-Amino-N-(2-bromo-4-methylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Amino-N-(2-bromo-4-methylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (CAS 625370-15-2), molecular formula C21H22BrN3OS and molecular weight 444.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-N-(2-bromo-4-methylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (C21H22BrN3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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).
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.
As a certified reference material (CRM), 3-Amino-N-(2-bromo-4-methylphenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide 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.
