Description

m-Peg7-Aldehyde CAS NO 1058691-77-2 is a functionalized polyethylene glycol derivative featuring a terminal aldehyde group, making it a versatile heterobifunctional linker for bioconjugation and polymer chemistry. Its core value lies in enabling the site-specific modification of biomolecules and materials through the reactive aldehyde moiety, which can form stable bonds with amines or hydrazides. This product is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require precise and controlled cross-linking strategies.

Application

• Bioconjugation Reagent: For the site-specific modification of proteins, peptides, and antibodies via reductive amination.
• PEGylation Linker: Used to create PEGylated drug conjugates to improve pharmacokinetics and solubility of therapeutic agents.
• Hydrogel Formation: Acts as a cross-linking agent in the synthesis of biocompatible hydrogels for drug delivery and tissue engineering.
• Surface Functionalization: For modifying nanoparticles, biosensors, and diagnostic assay surfaces to introduce aldehyde groups for further coupling.
• Polymer Synthesis: Serves as a macroinitiator or functional end-group in the synthesis of block copolymers and functionalized polymers.
• Diagnostic Kit Component: Used in the development of immunoassays and diagnostic probes requiring stable immobilization of capture molecules.

Quality Control

Our m-Peg7-Aldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Allow the sealed container to reach room temperature before opening to minimize condensation.
