Carboxyl Reactive

Payload Delivery Linkers and Modifiers | Uniform mPEG Modifiers: Carboxyl Reactive

Carboxyl-Reactive Uniform mPEG (methoxy polyethylene glycol) Modifiers are PEG derivatives designed with functional groups—such as primary amines or hydrazides—that selectively react with carboxylic acids to form stable amide or hydrazone bonds. These reagents enable site-specific PEGylation of proteins, peptides, or other carboxyl-containing molecules, enhancing solubility, stability, and circulation time. The uniform mPEG backbone ensures consistent molecular weight and performance in therapeutic, diagnostic, and surface modification applications.
