摘要：
Compound 1,1,1-trimethyl-2-(carboxyatoethyl)hydrazinium zwitterion (amphoteric ion) is a representative of new class of compounds. This compound has structure of betaine where positively charged group is a hydrazinium group. 1,1,1-Trimethyl-2-(carboxyatoethyl)hydrazinium zwitterion is obtained by passing spirit or water solution of 1,1,1-trimethyl-2-(2-alkoxycarbonylethyl)hydrazinium salt through column with strong basic anionite.Pieteikts 1,1,1-trimetil-2-(karboksilatoetil)hidrazFnija cviterjons, kas ir jaunas µFmisko savienojumu klases pLrstLvis, un tL ieg·°anas pa6miens. Savienojumam ir betaFna strukt·ra, kur pozitFvi lLd6tL grupa ir hidrazFnija grupa. 1,1,1-Trimetil-2-(2-karboksilatoetil)hidrazFnija cviterjonu ieg·st, lai²ot caur kolonnu ar stipri bLzisku anjonFtu 1,1,1-trimetil-2-(2-alkoksikarboniletil)hidrazFnija sLls spirta vai ·dens °µFdumu.
