m-PEG1-acid - CAS 2544-06-1
m-PEG1-acid (CAT: I032729) is a polyethylene glycol (PEG) derivative that features a terminal carboxylic acid group. This PEG derivative offers versatility in bioconjugation and drug delivery applications. The terminal carboxylic acid group can react with primary amine groups in the presence of activators like EDC (N-(3-Dimethylaminopropyl)-N’-ethylcarbodiimide) or DCC (N,N’-Dicyclohexylcarbodiimide) to form stable amide bonds. The hydrophilic PEG spacer enhances solubility in aqueous media, making m-PEG1-acid suitable for use in aqueous-based formulations.
