说明

一般說明

乙腈（Mecn），一种脂肪族腈，是一种具有宜人气味的无色液体。它在有机合成中被广泛用作溶剂和中间体。 它对紫外-可见光是透明的，使其非常适用于基于分光光度法和荧光测定的技术。因MeCN具有低粘度、高洗脱强度并在水中高度混溶，它在众多色谱技术中用作流动相组分。 它的红外光谱已被记录。 已研究了在铁络合物存在下通过利用过氧化氢的烷烃氧化而在MeCN中合成烷基氢过氧化物。 已研究了使用Co-B非晶态合金催化剂来氢化MeCN以形成乙胺。

應用

• Chromatographic Separation of Anthocyanins: Acetonitrile is a preferred solvent in high-performance liquid chromatography (HPLC) for the separation of anthocyanins and other phenolic compounds. Studies have explored the selectivity control of anthocyanin separation by replacing acetonitrile with methanol in the mobile phase, highlighting the solvent′s role in optimizing chromatographic conditions for improved resolution and detection sensitivity (Deineka et al., Journal of Analytical Chemistry, 2021).


• Peroxyoxalate Chemiluminescence Detection: Acetonitrile is used in peroxyoxalate chemiluminescence for the detection of α-amino acids. The solvent′s ability to form stable mixed solutions with water and ethyl acetate enhances the chemiluminescence reaction, allowing for sensitive and selective detection of amino acids in various samples. This application is essential for biochemical and clinical analyses (Kan et al., American Journal of Analytical Chemistry, 2020).


• Electrochemical Detection of DNA Modifications: Acetonitrile is utilized in electrochemical methods for detecting DNA modifications, such as 5-formyluracil. The solvent′s role in stabilizing the (2-benzimidazolyl) acetonitrile labeling reaction enhances the selectivity and sensitivity of detecting DNA modifications, which is crucial for genomic and biomedical research (Tang et al., Analytical Chemistry, 2021).


• Alternative Solvent in Chromatography: Research has investigated replacing acetonitrile with ethanol in reversed-phase HPLC for determining anthocyanins. This substitution aims to maintain chromatographic performance while reducing the environmental impact and costs associated with acetonitrile use. The findings demonstrate the feasibility of using ethanol as a greener alternative without compromising analytical quality (Deineka et al., Journal of Analytical Chemistry, 2023).
