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 N-[4-(Propan-2-yl)phenyl]thieno[2,3-b]quinoline-2-carboxamide.
N-[4-(Propan-2-yl)phenyl]thieno[2,3-b]quinoline-2-carboxamide (CAS 439111-78-1), molecular formula C21H18N2OS and molecular weight 346.45 g/mol, is a CATO reference standard with documented purity and traceability.
N-[4-(Propan-2-yl)phenyl]thieno[2,3-b]quinoline-2-carboxamide (C21H18N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
