Quality Control

Our production of 5,7-Dichloro-2-(5-Chloro-1,3-Dihydro-3-Oxo-2H-Indol-2-Ylidene)-1,2-Dihydro-3H-Indol-3-One adheres to stringent quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
