Quality Control

Our 2-((E)-2-(2-Chloro-3-[(E)-2-(1,3,3-Trimethyl-1,3-Dihydro-2H-Indol-2-Ylidene)Ethylidene]-1-Cyclopenten-1-Yl)Ethenyl)-1,3,3-Trimethyl-3H-Indolium Perchlorate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A detailed Certificate of Analysis (COA) is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flames. Due to its perchlorate salt nature and light-sensitive properties, it should be segregated from incompatible materials such as strong reducing agents and combustibles.
