Description

Poly-γ-Benzyl L-Glutamate is a synthetic polypeptide derived from the amino acid L-glutamic acid, where the γ-carboxyl group is protected by a benzyl ester. This compound matters as a key intermediate and model polymer in advanced materials research, particularly for studying polypeptide conformation and self-assembly. It is primarily needed by researchers and manufacturers in the pharmaceutical, biomedical, and specialty polymer industries for applications ranging from drug delivery systems to the development of biomimetic materials.

Application

• Biomedical Research: As a model compound for studying α-helix and β-sheet conformations of polypeptides.
• Drug Delivery Systems: A precursor or building block for designing biodegradable polymeric carriers for controlled drug release.
• Tissue Engineering: Used in the fabrication of scaffolds that mimic the extracellular matrix due to its polypeptide structure.
• Specialty Polymers: Serves as an intermediate in the synthesis of polyglutamic acid (PGA) and other functional polymers.
• Surface Modification: Employed to create bioactive or specific-interaction coatings on medical devices and implants.
• Material Science Studies: Investigated for its liquid crystalline properties and potential in creating ordered polymeric materials.

Quality Control

Our Poly-γ-Benzyl L-Glutamate is produced under controlled conditions to ensure batch-to-batch consistency. Quality is assured through rigorous analytical testing, including determination of molecular weight distribution, optical rotation, and residual solvent analysis. A comprehensive Certificate of Analysis (COA) detailing purity, specific rotation, and other critical parameters is provided with each shipment to support your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect the material's properties.
