N,7-Dimethyl-3-(phenylsulfonyl)-6,7,8,9-tetrahydropyrazolo[1,5-a]pyrido[3,4-e]pyrimidin-2-amine hydrochloride (CAS 1194574-68-9) is a high-purity analytical reference standard with the molecular formula C17H19N5O2SHCl and a molecular weight of 393.89 g/mol.
The molecular framework of N,7-Dimethyl-3-(phenylsulfonyl)-6,7,8,9-tetrahydropyrazolo[1,5-a]pyrido[3,4-e]pyrimidin-2-amine hydrochloride (C17H19N5O2SHCl) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
