1-Cycloheptyl-3-(2-methylquinolin-4-yl)-2-(thiazol-2-yl)guanidine (CAS 71079-62-4) is a high-purity analytical reference standard with the molecular formula C21H25N5S and a molecular weight of 379.52 g/mol.
The molecular framework of 1-Cycloheptyl-3-(2-methylquinolin-4-yl)-2-(thiazol-2-yl)guanidine (C21H25N5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
