This chemical is primarily used as a stationary phase in gas chromatography (GC) due to its unique selectivity for polar compounds. It is particularly effective in separating analytes with functional groups such as nitriles, esters, and alcohols. Its cyanopropyl groups provide strong interactions with polar molecules, making it suitable for analyzing complex mixtures in environmental, pharmaceutical, and food testing applications. Additionally, it is employed in specialized coatings and materials where its chemical resistance and thermal stability are advantageous.
