Chemical Structure
Description
The molecular framework of 4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-c]pyridin-3-ol dihydrochloride (C6H9N3OHCl) is characterized by an amide 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).
4,5,6,7-Tetrahydro-2H-pyrazolo[4,3-c]pyridin-3-ol dihydrochloride (CAS 1260898-28-9) is a high-purity analytical reference standard with the molecular formula C6H9N3OHCl and a molecular weight of 175.62 g/mol.
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.
