t-boc-N-amido-dPEG®4-OH, product number 10250, is a short, monodispersed PEGylation reagent. The reagent terminates with alcohol on one end of the single molecular weight, discrete-length PEG (dPEG®) chain and a boc-protected amine on the other end. This compound is a building block that permits other constructs with a short, discrete PEG in them.

Using Quanta BioDesign’s dPEG® Products

Quanta BioDesign’s dPEG® products are single molecular weight PEG products with discrete chain lengths. Unlike polymer PEG products, our products have no dispersity; that is, they are monodispersed. Moreover, we do not purify our dPEG® products from a polymeric mixture. Instead, we synthesize our products from high purity starting materials.

Frequently Asked Questions (about dPEG® products)

Using t-boc-N-amido-dPEG®4-OH

This product is useful for building novel constructs with dPEG® linkers. This product also permits supramolecular construction and unique side-chain modifications of amino acid residues in peptides.

The terminal alcohol of t-boc-N-amido-dPEG®4-OH can be transformed easily into a different functional group such as an aldehyde or acid. Moreover, the hydroxy group reacts with halide-functionalized compounds to form new products. For example, by reacting propargyl bromide with the terminal hydroxy group in the presence of a base, a dPEG® product with an aliphatic alkyne is formed. Thus, t-boc-N-amido-dPEG®4-OH is a building block for new constructs that incorporate a discrete-length PEGylation product.

The boc-protected amine easily deprotects with trifluoroacetic acid or another acid. The exposed amine may be reacted further or left unmodified.
