Chemical Structure

n-((1-Ethyl-1h-pyrazol-5-yl)methyl)-2-methylpropan-1-amine CAS 1343173-32-9 chemical structure

Description

n-((1-Ethyl-1h-pyrazol-5-yl)methyl)-2-methylpropan-1-amine (CAS 1343173-32-9), molecular formula C10H19N3 and molecular weight 181.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H19N3, n-((1-Ethyl-1h-pyrazol-5-yl)methyl)-2-methylpropan-1-amine contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 181.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
