Ald-PEG1-t-butyl ester can react with hydrazide and aminooxy groups which are commonly used in biomolecular probes for labeling and crosslinking carbonyls (oxidized carbohydrates). The t-butyl ester can be removed under acidic conditions for further conjugation.

Ald-PEG1-C2-Boc is an alkyl/ether-based PROTAC linker that can be used in the synthesis of PROTACs[1].
