Chemical Structure
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-6-ethyl-N-[2-(4-fluorophenyl)ethyl]-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide.
3-amino-6-ethyl-N-[2-(4-fluorophenyl)ethyl]-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (CAS 445268-94-0) is a high-purity analytical reference standard with the molecular formula C22H24FN3OS and a molecular weight of 397.51 g/mol.
3-amino-6-ethyl-N-[2-(4-fluorophenyl)ethyl]-5,6,7,8-tetrahydrothieno[2,3-b]quinoline-2-carboxamide (C22H24FN3OS) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
