Chemical Structure
Description
3-Benzhydryl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine (CAS 879072-51-2), molecular formula C19H19N3 and molecular weight 289.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Benzhydryl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine (C19H19N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 289.37 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
