Product Information

Description	AcS-PEG6-t-butyl ester is a PEG linker containing a sulfur acetyl group and a t-butyl ester. The sulfur acetyl group can be deprotected to form a thiol group. The t-butyl ester can be removed under acidic conditions. The hydrophilic PEG linker increases the water solubility of compounds in aqueous media.
Synonyms	S-acetyl-PEG6-t-butyl ester; S-acetyl-PEG6-Boc; tert-butyl 2-oxo-6,9,12,15,18,21-hexaoxa-3-thiatetracosan-24-oate; 4,7,10,13,16,19-Hexaoxa-22-thiatetracosanoic acid, 23-oxo-, 1,1-dimethylethyl ester; 2-Methyl-2-propanyl 2-oxo-6,9,12,15,18,21-hexaoxa-3-thiatetracosan-24-oate; 6,9,12,15,18,21-Hexaoxa-3-thiatetracosan-24-oic acid, 2-oxo-, 1,1-dimethylethyl ester
