white powder | [Uses]
2-Bromo-2-methylpropionic acid is used in the Herceptin functionalization of polyhedral oligomeric silsesquioxane-conjugated oligomers-silica /iron oxide nanoparticles for tumor cell sorting.
| [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. | [General Description]
