2-Bromoisobutyric acid, 98%

Description

CAS: 2052-01-9 | C4H7BrO2 | 167.00 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
