Quality Control

Our Poly(β-Benzyl-L-Aspartate-Co-L-Leucine) is produced under stringent quality management protocols. Each batch is characterized to ensure consistent molecular weight distribution, copolymer composition, and purity, meeting the exacting standards required for research and advanced material synthesis. Certificates of Analysis (COA) detailing specifications such as inherent viscosity, monomer ratio, and residual solvent levels are provided with every shipment.

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 (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider using a desiccant.
