Product Information

Description	CHO-Ph-CONH-PEG4-COOtBu contains a benzaldehyde group that 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. The hydrophilic PEG linker increases the water solubility of the compound.
Synonyms	Ald-Ph-PEG4-t-butyl ester; DF-PEG4-CH2CH2COOtBu; Ald-Ph-amido-PEG4-C2-Boc; Ald-Ph-PEG4-CH2CH2COOtBu; Ald-Ph-PEG4-COOtBu; tert-Butyl 1-(4-formylphenyl)-1-oxo-5,8,11,14-tetraoxa-2-azaheptadecan-17-oate; 4,7,10,13-Tetraoxa-16-azaheptadecanoic acid, 17-(4-formylphenyl)-17-oxo-, 1,1-dimethylethyl ester; 2-Methyl-2-propanyl 1-(4-formylphenyl)-1-oxo-5,8,11,14-tetraoxa-2-azaheptadecan-17-oate; 5,8,11,14-Tetraoxa-2-azaheptadecan-17-oic acid, 1-(4-formylphenyl)-1-oxo-, 1,1-dimethylethyl ester
