Chemical Structure
Description
CATO supplies (1S,3S,5S,6R,8S)-3-Ethyl-5-(6-methoxyquinolin-4-yl)-4-oxa-1-azatricyclo[4.4.0.03,8]decane (CAS 205495-11-0), a certified reference material (molecular formula C20H24N2O2, MW 324.42 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (1S,3S,5S,6R,8S)-3-Ethyl-5-(6-methoxyquinolin-4-yl)-4-oxa-1-azatricyclo[4.4.0.03,8]decane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
