Chemical Structure
Description
The occurrence of N-((1-ethyl-5-methyl-1H-pyrazol-4-yl)methyl)ethanamine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-((1-ethyl-5-methyl-1H-pyrazol-4-yl)methyl)ethanamine (CAS 956935-38-9) is a high-purity analytical reference standard with the molecular formula C9H17N3 and a molecular weight of 167.25 g/mol.
The molecular framework of N-((1-ethyl-5-methyl-1H-pyrazol-4-yl)methyl)ethanamine (C9H17N3) is characterized by a nitrile group. 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. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
