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-(4-bromo-2-fluorophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide.
CATO supplies 3-Amino-N-(4-bromo-2-fluorophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (CAS 625370-21-0), a certified reference material (molecular formula C20H19BrFN3OS, MW 448.35 g/mol) for analytical method development and quality control.
Structurally, 3-Amino-N-(4-bromo-2-fluorophenyl)-6-ethyl-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (C20H19BrFN3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine 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 448.35 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
