The goal of chemical derivatization is to modify the structure of the analyte(either a nucleophile or electrophile) using a chemical reagent(either an electrophile or nucleophile depending on the nature of the analyte) and, as a result, a new compound(the reaction's derivate) with improved chemical and physical properties for analysis is formed. 1, record 1, English, - chemical%20derivatization
Record number: 1, Textual support number: 1 OBS
It should be noted that chemical derivatisation usually means that the alteration of a compound by means of a chemical reaction (or reactions) leaves essential parts of the parent molecule unchanged ... 2, record 1, English, - chemical%20derivatization
