Tert-butyl (R)-3-(4-amino-3-iodo-1H-pyrazolo[4,3-c]pyridin-1-yl)piperidine-1-carboxylate (CAS 2056025-28-4) is a high-purity analytical reference standard with the molecular formula C16H22IN5O2 and a molecular weight of 443.28 g/mol.
The molecular framework of Tert-butyl (R)-3-(4-amino-3-iodo-1H-pyrazolo[4,3-c]pyridin-1-yl)piperidine-1-carboxylate (C16H22IN5O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine 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.
