Chemical Structure
Description
N-((1-Cyclopentyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-propyl-1H-pyrazol-3-amine hydrochloride (CAS 1856072-39-3) is a high-purity analytical reference standard with the molecular formula C16H25N5HCl and a molecular weight of 323.87 g/mol.
N-((1-Cyclopentyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-propyl-1H-pyrazol-3-amine hydrochloride (C16H25N5HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), N-((1-Cyclopentyl-3-methyl-1H-pyrazol-4-yl)methyl)-1-propyl-1H-pyrazol-3-amine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
