Chemical Structure
Description
CATO supplies 5-Amino-3-cyclohexyl-1-ethyl-1H-pyrazole-4-carbonitrile (CAS 553672-26-7), a certified reference material (molecular formula C12H18N4, MW 218.30 g/mol) for analytical method development and quality control.
Structurally, 5-Amino-3-cyclohexyl-1-ethyl-1H-pyrazole-4-carbonitrile (C12H18N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 218.30 g/mol, it falls into the medium-molecular-weight range. 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.
