Product Information
| Description | Azido-PEG4-propionic acid is a specialized heterobifunctional reagent featuring an azide group and a short polyethylene glycol (PEG) spacer linked to a propionic acid moiety. The azido functionality facilitates efficient click chemistry reactions, enabling site-specific conjugation to alkyne-containing molecules. The PEG4 spacer imparts enhanced aqueous solubility and reduces steric hindrance, which is beneficial in peptide modification and surface functionalization studies. Frequently utilized in bioconjugation, proteomics, and targeted delivery research, this compound supports precise molecular design and advanced chemical biology applications. |
