(2-Pyridyldithio)-PEG4-Acid (CAS: 581065-93-2)
(2-Pyridyldithio)-PEG4-Acid acts as a heterobifunctional linker for bioconjugation and drug development. Its 2-pyridyldithiol group reacts with thiols to form disulfide bonds, while its terminal carboxylic acid couples with amine-containing molecules. The PEG4 spacer increases solubility and flexibility, reducing steric hindrance during conjugation.
Key Features:
- Functional Groups: 2-pyridyldithiol enables thiol reactivity, and the carboxylic acid facilitates amine coupling.
- PEG4 Spacer: Increases solubility and provides flexibility for efficient conjugation.
Applications:
- Bioconjugation: Links biomolecules through thiol-disulfide exchange and amide bond formation.
- Drug Development: Functions as a linker in synthesizing antibody-drug conjugates (ADCs) and targeted therapies.
Handling and Storage:
- Molecular Formula: C₁₆H₂₅NO₆S₂
- Molecular Weight: 391.50 g/mol
- Storage: Keep in a cool, dry place, away from light and moisture.
