Description

2-[2-(Boc-amino)ethoxy]ethoxyacetic acid dicyclohexylammonium salt is a protected, monodisperse polyethylene glycol spacer comprising two ethylene oxide units, a Boc-protected amino group at one end, and a carboxylic acid at the other, supplied as its crystalline dicyclohexylammonium salt.

Applications

Used as a hydrophilic spacer and linker building block in peptide synthesis, bioconjugation, and the preparation of PEGylated peptides and drug conjugates.

Product Overview

The Boc group is removed under acidic conditions to reveal the amino terminus for coupling, while the carboxyl group can be activated for amide bond formation. The dicyclohexylammonium salt form offers improved crystallinity and handling compared with the free acid.
