Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay, impurity profile, and moisture content are available upon request. We adhere to a cGMP-compliant quality management system to guarantee reliability for research and development 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 (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from moisture absorption.
