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.
3-(1H-Pyrazol-1-yl)-N-[3-(1H-pyrazol-1-yl)propyl]-1-propanamine oxalate (CAS 1421769-48-3) is a high-purity analytical reference standard with the molecular formula C12H19N5C2H2O4 and a molecular weight of 323.35 g/mol.
The molecular framework of 3-(1H-Pyrazol-1-yl)-N-[3-(1H-pyrazol-1-yl)propyl]-1-propanamine oxalate (C12H19N5C2H2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
