Product Information

Description 3,4-Dibromo-Mal-PEG12-COOH is a PEG linker with a dibromomaleimide group and an acid group. The dibromomaleimide group allows for two points of substitution due to the two bromine atoms. The carboxylic acid can react with primary amines in the presence of EDC and HATU to form a stable amide bond. The hydrophilic PEG linker increases the water solubility of compounds in aqueous media.
Synonyms 3,4-Dibromo-Mal-PEG12-acid; 1-(3,4-dibromo-2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacontan-39-oic acid
