Description

H2N-Peg9-Oh CAS NO 15332-95-3 is a high-purity, amine-terminated polyethylene glycol (PEG) derivative, specifically a nonaethylene glycol monoamine. This bifunctional molecule is a critical building block in bioconjugation and pharmaceutical development, offering a hydrophilic spacer arm to improve solubility and reduce immunogenicity. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and advanced materials sectors who require reliable, high-quality linkers for creating PEGylated therapeutics, diagnostic agents, and functionalized surfaces.

Application

• Bioconjugation and PEGylation: A primary linker for attaching drugs, proteins, peptides, or fluorescent dyes to enhance pharmacokinetic properties, solubility, and stability.
• Pharmaceutical Intermediates: Serves as a key raw material in the synthesis of antibody-drug conjugates (ADCs), peptide therapeutics, and other advanced drug delivery systems.
• Surface Functionalization: Used to modify nanoparticles, quantum dots, biosensors, and medical device surfaces with amine-reactive groups for subsequent biomolecule attachment.
• Crosslinking Agent: Employed in the preparation of hydrogels, polymer networks, and biomaterials where a hydrophilic, amine-reactive spacer is required.
• Diagnostic Reagent Synthesis: A precursor for creating contrast agents, imaging probes, and assay components in diagnostic applications.
• Research & Development: A versatile tool in academic and industrial R&D for exploring new therapeutic modalities and material science applications.

Quality Control

Our H2N-Peg9-Oh is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
