Ald-Ph-PEG4-t-butyl ester Chemical Properties, Uses, Production

Description

Ald-Ph-PEG4-t-butyl ester contains a benzaldehyde group which can react with aminooxy (ONH2) bearing molecules. The t-butyl ester is a protecting group that can be removed under acidic conditions for further conjugation, PEG space improve aqueous solubility.

Uses

Ald-Ph-PEG4-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

IC 50

PEGs; Alkyl/ether
