Description

Polyasparagine is a synthetic poly(amino acid) derived from the amino acid L-asparagine, known for its biocompatibility and unique structural properties. This polymer is valued for its ability to form stable, water-soluble structures and its functional amine side chains, which make it a versatile platform for chemical modification. It serves as a critical intermediate and functional material in advanced pharmaceutical research, cosmetic formulations, and specialty polymer synthesis, where precise molecular architecture is required.

Application

• Pharmaceutical Research & Drug Delivery: Used as a biodegradable and biocompatible carrier for controlled-release drug formulations and as a building block for peptide-mimetic polymers.
• Cosmetic & Personal Care Ingredients: Functions as a film-forming agent, moisturizer, or conditioning polymer in advanced skincare and haircare products due to its humectant properties.
• Biomedical Materials: Serves as a substrate or coating for tissue engineering scaffolds and diagnostic devices, leveraging its protein-like structure.
• Specialty Polymer Synthesis: Acts as a precursor or comonomer for creating novel polyamides, hydrogels, and smart materials with responsive behavior.
• Agricultural Adjuvants: Utilized in the formulation of biodegradable coatings for seeds or agrochemicals to enhance efficacy and environmental compatibility.
• Research & Development: Employed in academic and industrial labs as a standard or model compound for studying polyamino acid behavior and interactions.

Quality Control

Our Polyasparagine is manufactured under a strict quality management system. Each batch is characterized for critical parameters including molecular weight distribution (by GPC), degree of polymerization, and residual monomer content (by HPLC). We provide comprehensive Certificates of Analysis (COA) detailing purity, identity (IR, NMR), and specific performance indicators relevant to your application. Our quality commitment ensures batch-to-batch consistency for your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent moisture absorption and potential degradation. For long-term storage, consider using desiccants.
