Product Information

Description	BrCH2CONH-PEG6-NHS ester is a PEG linker containing a bromide group and an NHS ester. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules.
Synonyms	Bromoacetamido-PEG6-C2-NHS ester; Bromoacetamido-PEG6-NHS ester; 2,5-dioxopyrrolidin-1-yl 1-bromo-2-oxo-6,9,12,15,18,21-hexaoxa-3-azatetracosan-24-oate; 2-Bromo-N-{21-[(2,5-dioxo-1-pyrrolidinyl)oxy]-21-oxo-3,6,9,12,15,18-hexaoxahenicos-1-yl}acetamide; Acetamide, 2-bromo-N-[21-[(2,5-dioxo-1-pyrrolidinyl)oxy]-21-oxo-3,6,9,12,15,18-hexaoxaheneicos-1-yl]-
