Chemical Structure
Description
Structurally, 1-[(1-ethyl-1H-pyrazol-4-yl)methyl]-1H-pyrazol-4-amine,2HCl (C9H13N5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 227.70 g/mol, it falls into the medium-molecular-weight range. 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).
1-[(1-ethyl-1H-pyrazol-4-yl)methyl]-1H-pyrazol-4-amine,2HCl (CAS 1431966-11-8), molecular formula C9H13N5HCl and molecular weight 227.70 g/mol, is a CATO reference standard with documented purity and traceability.
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.
