Amino-PEG1-acid (NH2-PEG-COOH) (CAS: 144942-89-2) is a bifunctional molecule with both an amine (NH2) group and a carboxylic acid (COOH) group. The PEG1 spacer between these groups adds flexibility and water solubility. It works well in bioconjugation, surface modification, and polymer cross-linking.
Key Features:
- Amine Group (NH2): Easily reacts with carboxyl or isocyanate groups, facilitating bond formation.
- Carboxylic Acid Group (COOH): Allows conjugation with amines or alcohols through amide or ester bonds.
- PEG1 Spacer: Adds flexibility and boosts solubility in water-based environments.
Key Applications:
- Bioconjugation: Effectively links biomolecules like proteins or peptides using its amine or carboxyl groups.
- Surface Modification: Modifies surfaces such as nanoparticles or other materials for specific functions.
- Polymer Cross-Linking: Connects polymers to enhance stability or add functionality.
This compound is highly versatile and suited for many chemical modifications in biological and material science fields.
