Amino-PEG9-t-butyl ester Chemical Properties,Usage,Production

Description

Amino-PEG9-t-butyl ester is a PEG molecule with an amino group and a t-butyl protected carboxyl group (tBoc). 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-butyl protected carboxyl group can be deprotected under acidic conditions.

Uses

Amino-PEG9-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

IC 50

PEGs; Alkyl/ether
