Chemical Structure
Description
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.
2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine dihydrochloride (CAS 1171476-07-5), molecular formula C12H13N3HCl and molecular weight 235.72 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H13N3HCl, 2-phenyl-4,5,6,7-tetrahydro-2H-pyrazolo[4,3-c]pyridine dihydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 235.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
