1-(4-chlorobenzyl)-3-methyl-1H-pyrazol-5-amine,HCl CAS 1431964-92-9 chemical structure

Description

The occurrence of 1-(4-chlorobenzyl)-3-methyl-1H-pyrazol-5-amine,HCl is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-chlorobenzyl)-3-methyl-1H-pyrazol-5-amine,HCl (CAS 1431964-92-9), molecular formula C11H12ClN3HCl and molecular weight 258.15 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-chlorobenzyl)-3-methyl-1H-pyrazol-5-amine,HCl (C11H12ClN3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
