CAS number：1530777-90-2 molecular formula：C25H42O11S
Tos-PEG7-CH2CO2tBu is a PEG derivative containing a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The tosyl group is a very good leaving group for nucleophilic substitution reactions.
