What is α,ω-dipropionic acid tetraethylene glycol?
Description
Bis-PEG5-acid is a PEG linker containing two terminal carboxylic acid groups. The hydrophilic PEG spacer increases solubility in aqueous media. The terminal carboxylic acids can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.
The Uses of α,ω-dipropionic acid tetraethylene glycol
As a dicarboxylic acid, 4,7,10,13,16-Pentaoxanonadecanedioic Acid can be used in the preparation of potent dimeric inhibitors of the PSD-95-NMDA receptor interaction.
