Quality Control

Our 2-((E)-2-[3-[(E)-2-(3,3-Dimethyl-1-phenyl-1,3-dihydro-2H-indol-2-ylidene)ethylidene]-2-(1-naphthyl)-1-cyclopenten-1-yl]ethenyl)-3,3-dimethyl-1-phenyl-3H-indolium perchlorate is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and elemental analysis. We provide a detailed Certificate of Analysis (COA) with each shipment, ensuring traceability and compliance with your research or production specifications.

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 perchlorate salt nature and light-sensitive properties, keep away from heat, sparks, open flames, and incompatible materials such as strong reducing agents and combustible organics. Ensure good ventilation in the storage area.
