Chemical Structure
Description
1-(1-(2-Fluoroethyl)-1H-pyrazol-3-yl)-N-((1-isopropyl-1H-pyrazol-5-yl)methyl)methanamine hydrochloride (CAS 1856025-98-3), molecular formula C13H20FN5HCl and molecular weight 301.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 1-(1-(2-Fluoroethyl)-1H-pyrazol-3-yl)-N-((1-isopropyl-1H-pyrazol-5-yl)methyl)methanamine hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
