Product Information
| Description | Tos-PEG2-COOtBu linker bears a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases the solubility in aqueous media. The carboxyl group protected by tert-butyl can be deprotected under acidic conditions. Tosyl group is a very good leaving group for nucleophilic substitution reaction. |
| Synonyms | tert-butyl 3-(2-(tosyloxy)ethoxy)propanoate; 2-(2-(tert-Butoxycarbonyl)ethoxy)ethyl 4-methylbenzenesulfonate; Tos-PEG2-t-butyl ester; Tos-PEG2-Boc |
