Description

Mpeg7-Ch2Ch2Cooh CAS NO 1093647-41-6 is a specialized functionalized polyethylene glycol (PEG) derivative, designed as a versatile linker and modifier for advanced material synthesis. This compound matters for its ability to introduce carboxylic acid functionality and PEGylation, which are critical for enhancing solubility, biocompatibility, and conjugation efficiency in complex formulations. It is essential for researchers and manufacturers in the pharmaceutical, bioconjugation, and advanced polymer industries who require precise surface modification and controlled chemical attachment.

Application

• Pharmaceutical Conjugation: Acts as a heterobifunctional linker for attaching drugs, peptides, or targeting ligands to nanoparticles, antibodies, or other biologics.
• Biomaterial Surface Modification: Used to functionalize medical devices, implants, or diagnostic surfaces with hydrophilic, non-fouling PEG layers via the terminal carboxylic acid group.
• Polymer Chemistry: Serves as a macro-initiator or co-monomer in the synthesis of amphiphilic block copolymers for micelle or hydrogel formation.
• Diagnostic Reagent Preparation: Employed in the development of assay components, such as enzyme or fluorescent dye conjugates, to improve stability and performance.
• Nanoparticle Functionalization: Crucial for coating quantum dots, liposomes, or metallic nanoparticles to improve colloidal stability and provide a handle for further bioconjugation.
• Cross-linking Agent: Utilized in the creation of cross-linked networks or hydrogels where the carboxylic acid groups can be activated for amide bond formation.

Quality Control

Our Mpeg7-Ch2Ch2Cooh is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity suitable for sensitive applications. Each lot undergoes comprehensive analytical characterization, including HPLC, NMR, and titration methods, to confirm identity, assay, and impurity profiles. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with our stringent specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. Due to its hygroscopic nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from strong oxidizing agents.
