m-PEG10-CH2COOH(CAT: I016293) is a monofunctional polyethylene glycol derivative containing a carboxymethyl group at one terminus of a 10-unit PEG chain, with the other end capped by a methoxy group. The carboxylic acid functionality enables straightforward conjugation to amines or other reactive groups through amide bond formation or esterification. The PEG10 spacer provides hydrophilicity, flexibility, and enhanced solubility, helping to reduce non-specific interactions and improve stability of conjugated molecules. This reagent is commonly used in bioconjugation, surface modification, drug delivery, and polymer research where a single reactive site and controlled spacing are required.
