Mal-PEG4-t-butyl ester - 98%, high purity , CAS No.518044-36-5
Basic Description Synonyms Mal-PEG4-t-butyl ester | LCZC2677 | Mal-PEG4-CH2CH2COOtBu | tert-Butyl1-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)-3,6,9,12-tetraoxapentadecan-15-oate | Mal-PEG4-COOtBu | HY-130469 | MS-26830 | SCHEMBL18059965 | tert-butyl 15-maleimido-4,7,10,13-tetraoxapenta Specifications & Purity ≥98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Mal-PEG4-t-butyl ester is a PEG derivative containing a maleimide group and a t-butyl ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
