Abstract

This is the first of two reviews devoted to derivatization approaches for "soft" ionization mass spectrometry (FAB, MALDI, ESI, APCI) and deals, in particular, with small molecules. The principles of the main "soft" ionization mass spectrometric methods as well as the reasons for derivatizing small molecules are briefly described. Derivatization methods for modification of amines, carboxylic acids, amino acids, alcohols, carbonyl compounds, monosaccharides, thiols, unsaturated and aromatic compounds etc. to improve their ionizability and to enhance structure information content are discussed. The use of "fixed"-charge bearing derivatization reagents is especially emphasized. Chemical aspects of derivatization and "soft" ionization mass spectrometric properties of derivatives are considered.

摘要

这是两篇关于“软”电离质谱(FAB、MALDI、ESI、APCI)衍生化方法的综述中的第一篇,尤其涉及小分子。简要描述了主要“软”电离质谱方法的原理以及小分子衍生化的原因。讨论了用于修饰胺、羧酸、氨基酸、醇、羰基化合物、单糖、硫醇、不饱和及芳香族化合物等的衍生化方法,以提高其离子化能力并增强结构信息含量。特别强调了使用带有“固定”电荷的衍生化试剂。考虑了衍生化的化学方面以及衍生物的“软”电离质谱性质。
