Chemical Structure
Description
1-Methyl-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine hydrochloride (CAS 2098717-79-2) is a high-purity analytical reference standard with the molecular formula C7H11N3HCl and a molecular weight of 173.64 g/mol.
Based on its molecular formula C7H11N3HCl, 1-Methyl-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine hydrochloride contains a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
