Quality Control

Our ε-Pyrromycinone is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as identity, purity, and impurity profile. We support compliance with cGMP guidelines for pharmaceutical intermediates, and specifications can be aligned with customer-specific 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, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers.
