Quality Control

Our Antibiotic U-12,241 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets high-grade pharmaceutical standards. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability, consistency, and compliance with your research or production requirements.

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 light-sensitive and easily oxidized nature (store under inert atmosphere), it is recommended to handle under an inert atmosphere such as nitrogen or argon for long-term storage and to minimize headspace in opened containers.
