Quality Control

Our Indole-4,7-Dione is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for all shipments. We support compliance with relevant research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated 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 (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
