m-PEG3-CH2CH2COOH is a methoxy-terminated PEG3 carboxylic acid used as a short, flexible spacer for bioconjugation chemistry. It is employed as a non-cleavable linker in antibody-drug conjugate (ADC) assembly and as a PEG-based linker in PROTAC and other conjugation workflows, providing a terminal carboxylic acid for coupling reactions and improving solubility of conjugates.
- Methoxy-terminated PEG3 spacer providing flexibility.
- Terminal carboxylic acid suitable for amide coupling and esterification.
- Molecular weight 236.26 g·mol⁻¹ for predictable spacer length.
- High purity (approximately 97.0%) suitable for research applications.
- Available in small research-scale quantities and recommended refrigerated storage for stability.
