Quality Control

Our Candicidin is produced and tested under strict quality management systems to ensure it meets the stringent requirements for pharmaceutical intermediates. Each batch is subjected to comprehensive analytical testing, including identity, purity, and potency assays. A Certificate of Analysis (COA) detailing all test results is provided to guarantee traceability and compliance with relevant specifications.

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 sensitivity to oxidation, it is recommended to store the product under an inert atmosphere for long-term stability. Keep the container tightly sealed in a dry environment to prevent moisture absorption.
