The invention provides compositions and methods for mass spectrometric (MS), organic synthesis, and applications of organo-trifluoroborate, for example, as mass tags for use in negative ion mode. When subject to MS fragmentation, organo-trifluoroborates preferentially undergo neutral losses of hydrogen fluoride (HF) or boron trifluoride (BF
3
) molecules, transferring the negative charge to the rest of the molecule. Such a fragmentation pattern is used to detect and quantitate analytes of interest after derivatization with organo-trifluoroborates.
这项发明提供了用于质谱(MS)、有机合成以及有机三氟硼酸盐的应用的组合物和方法,例如作为质谱负离子模式下使用的质量标记。在经历MS碎裂时,有机三氟硼酸盐优先发生氢氟酸(HF)或三氟化硼(BF3)分子的中性损失,将负电荷转移到分子的其余部分。这样的碎裂模式用于在与有机三氟硼酸盐衍生化之后检测和定量感兴趣的分析物。
