TCO-Amine, HCl Salt
A building block used for derivatizing carboxyl groups in the presence of activators (e.g. EDC, or DCC) or activated esters (e.g. NHS esters) with TCO moiety through a stable amide bond. A short spacer arm adds minimal mass to modified molecules (262.8 daltons). TCO-Amine is supplied as specially formulated HCl salt (crystalline) for easy handling and extended shelf life.
