Chemical Structure
Description
CATO supplies 1-(4-Ethynylphenyl)cyclopropane-1-carbonitrile (CAS 869977-87-7), a certified reference material (molecular formula C12H9N, MW 167.21 g/mol) for analytical method development and quality control.
1-(4-Ethynylphenyl)cyclopropane-1-carbonitrile (C12H9N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
