Amino-PEG1-t-Butyl ester Chemical Properties, Uses, Production

Description

Amino-PEG1-t-butyl ester is a PEG reagent containing an amino group with a t-butyl protected carboxyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The t-Boc group can be deprotected under acidic conditions.

Uses

Amino-peg1-t-butyl Ester is a reagent used in the preparation of β2 adrenergic receptor agonists and muscarinic receptor activity antagonists.
