Quality Control

Our Rezafungin is manufactured under strict quality systems suitable for pharmaceutical development. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, identification by spectroscopic methods, and stringent control of impurities and residual solvents. Certificates of Analysis (COA) are provided and traceable to reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 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.
