Chemical Structure
Description
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.
N-Isopentyl-1-isopropyl-1H-pyrazol-5-amine hydrochloride (CAS 1855946-87-0), molecular formula C11H21N3HCl and molecular weight 231.77 g/mol, is a CATO reference standard with documented purity and traceability.
N-Isopentyl-1-isopropyl-1H-pyrazol-5-amine hydrochloride (C11H21N3HCl) contains 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 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.
