(S)-3-(4-(7-Methoxyquinolin-8-yl)-1,4-diazepan-1-yl)-3-(2-morpholinothiazol-4-yl)-N-(2-(pyrrolidin-1-yl)ethyl)propanamide (CAS 1257861-17-8), molecular formula C31H43N7O3S and molecular weight 593.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (S)-3-(4-(7-Methoxyquinolin-8-yl)-1,4-diazepan-1-yl)-3-(2-morpholinothiazol-4-yl)-N-(2-(pyrrolidin-1-yl)ethyl)propanamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 593.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
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.
