Medchemexpress LLC Maleimido-tri(ethylene glycol)-propionic acid | 518044-40-1 | MFCD23103943 | 98.0% | 301.29 g/mol | C13H19NO7 | 250 MG
Maleimido-tri(ethylene glycol)-propionic acid is a PEG-based maleimide linker used for site-specific cysteine conjugation in bioconjugation workflows. It combines a maleimide reactive group, a triethylene glycol spacer, and a propionic acid terminus to improve solubility and enable downstream coupling reactions.
- Provides a maleimide reactive group for cysteine-specific conjugation.
- Contains a triethylene glycol spacer to increase solubility and flexibility.
- Features a terminal propionic acid for further derivatization or coupling.
- Suitable for ADC linker synthesis and PEG-based PROTAC linkers.
- Available in small research pack sizes, including 250 mg.
