It is used as a non-cleavable three-unit PEG spacer for antibody-drug conjugate (ADC) and PROTAC synthesis, and as an azide reagent for click chemistry reactions such as CuAAC and SPAAC.
- Bifunctional aminooxy and azide groups for oxime ligation and click chemistry.
- Non-cleavable three-unit PEG spacer suitable for ADC and PROTAC linker installation.
- Purity 95.0% and molecular weight 234.25 g/mol.
- Appearance colorless to light yellow liquid for easy handling.
- Storage: pure form -20°C (stable 3 years); in solvent -80°C (6 months) or -20°C (1 month).
- Available in small pack sizes, including 10 mg for small-scale synthesis.
