Quality Control

Our Poly-β-Benzyl L-Aspartate is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including NMR, GPC (for molecular weight distribution), and HPLC. A comprehensive Certificate of Analysis (COA) detailing purity, molecular weight parameters, and residual solvent levels is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
