The present invention provides a compound of the formula: (IIa); having a reactive functional group M, capable of reacting with a biopolymer, BP, having at least one group capable of reacting with M to form a covalent linkage, to provide a biopolymer derivative of the formula: (IIIa). The biopolymer derivatives of the invention have enhanced ionisability with respect to free 10 biopolymer (Bp) enabling improved analysis of the biopolymer using mass spectrometry. The invention further provides specific examples of compounds formula (IIa), e.g. compounds of formula: (IIa-2
a
) and (IIa-58
a
).
本发明提供了一种化合物,其化学式为:(IIa),具有反应性功能基团M,能够与生物聚合物BP反应,BP具有至少一个能够与M反应形成共价键的基团,从而提供化合物的生物聚合物衍生物,其化学式为:(IIIa)。本发明的生物聚合物衍生物相对于自由生物聚合物(Bp)具有增强的离子化能力,从而能够通过质谱分析获得更好的分析结果。本发明还提供了化合物化学式(IIa)的具体例子,例如化合物化学式:(IIa-2a)和(IIa-58a)。
