A new method is proposed for the permanent-charge generation derivatization of thiols of different structures by a reaction with haloalkanes and dibromides. It was shown that 1,4-dibromobutane and 1,2-xylylene dibromide are the most effective alkylat

In recent years, a special focus is placed on the usage of reactive matrices for analytical matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS). Since 2003, when the term "reactive matrices" was suggested and the dignity of compo
