Quality Control

Our Hpa Ii is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters such as assay (HPLC), related substances, and residual solvents, supporting its use in regulated environments. Specifications can be aligned with client requirements for research or cGMP applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat and incompatible materials.
