Chiral derivatizing agent
CDA must not racemize under derivatization or analysis conditions. Double-derivatization is generally considered more accurate, but single-derivatization usually requires less reagents and, thus, is more cost effective wikipedia.org

Edman degradation
The peptide length is limited due to the cyclical derivatization not always going to completion. The derivatization problem can be resolved by cleaving large peptides into smaller peptides before proceeding with the reaction. wikipedia.org

Derivatization for liquid chromatography-electrospray ionization-mass ...
1. Introduction. Analysis of trace small-molecule compounds in complex samples is a challenge. Liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) is the most prominent analytical platform for small-molecule compounds analysis by virtue of the strong separation capability of LC, good universality of ESI source, and high selectivity and sensitivity of MS [1], [2], [3], [4].

使用Waters AccQ•Tag化学品进行氨基酸衍生化处理 | Waters
如果氨基酸溶液可溶于0.1 N HCl中，则可以将10-20 µL样品直接转移至衍生化混合物中，而无需调节pH。注：仍然需要确保可用的衍生化试剂过量，如下所述。 如果氨基酸溶液中含有较高浓度的酸(>0.1 N HCl)，则应使用等体积、相同浓度的氢氧化钠进行中和。
