Description
CATO supplies 6-[(E)-2-(4-Methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]-2-(prop-2-yn-1-ylsulfanyl)pyridine-3-carbonitrile (CAS 303985-49-1), a certified reference material (molecular formula C27H22N2S, MW 406.54 g/mol) for analytical method development and quality control.
6-[(E)-2-(4-Methylphenyl)ethenyl]-4-[(Z)-2-(4-methylphenyl)ethenyl]-2-(prop-2-yn-1-ylsulfanyl)pyridine-3-carbonitrile (C27H22N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
