一般描述
乙腈（MeCN，ACN）是一种脂肪族腈，通常用作反应溶剂以及有机合成中的化学中间体。由于MeCN低粘度、高洗脱强度和在水中的混溶性，在许多色谱技术中它被用作流动相溶剂。
应用
乙腈可作为溶剂，用于：
- 固相多肽合成。
- 唾液酸化反应。
- 用NaBH4还原硝酸铜盐合成铜纳米颗粒。在制备过程中，乙腈作为保护溶剂，防止纳米颗粒的氧化。
- 通过Cu催化芳基碘和二苯基二硒醚的偶联反应制备二芳基硒醚。在此过程中，ACN也作为铜催化剂的配体，以增加其催化活性。
特点和优势
ACS溶剂品质满足或超过美国化学学会(ACS)的高标准，每种化合物都具有特定的检验规格。根据美国化学学会标准，ACS试剂级代表物质纯度足够用于大多数化学分析或反应。

Protein complexes represent major functional units for the execution of biological processes. Systematic affinity purification coupled with mass spectrometry (AP-MS) yielded a wealth of information on the compendium of protein complexes expressed in Saccharomyces cerevisiae. However, global AP-MS analysis of

The neuropathological substrate of dementia in patients with Parkinson's disease is still under debate, particularly in patients with insufficient alternate neuropathology for other degenerative dementias. In patients with pure Lewy body Parkinson's disease, previous post-mortem studies have shown that dopaminergic
