Quality Control

Our 4-Aminobenzoyl-Poly-γ-Glutamate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as degree of substitution, molecular weight distribution, and impurity profiles are available upon request. We adhere to cGMP principles for pharmaceutical-grade material where applicable.

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. For long-term stability, consider storage under an inert atmosphere such as nitrogen or argon.
