Description and Uses

2-Bromoisobutyric acid is used in the synthesis of dextran macroinitiator for atom transfer radical polymerization (ATRP) by partial esterification of hydroxyl group of the polysaccharide. The multifunctional silica colloids were prepared by coating them with 2-bromo-2-methylpropionic acid stabilized quantum dots.
