Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-N-(3-bromophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide.
CATO supplies 3-Amino-N-(3-bromophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (CAS 445268-93-9), a certified reference material (molecular formula C20H20BrN3OS, MW 430.36 g/mol) for analytical method development and quality control.
3-Amino-N-(3-bromophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (C20H20BrN3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(3-bromophenyl)-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.
