Quality Control

Our 1,1',3,3,3',3'-Hexamethylindodicarbocyanine Perchlorate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and spectrophotometry for key optical properties. Certificates of Analysis (COA) detailing batch-specific results are available upon request to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a freezer at -20°C to -10°C under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation and moisture absorption. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation.
