Quality Control

Our production of 3,3'-Diethyl-2,2'-Thiadicarbocyanine Perchlorate adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability for research and industrial applications. Each lot undergoes comprehensive analytical testing, including HPLC for purity, UV-Vis spectroscopy for absorbance verification, and identity confirmation. A detailed Certificate of Analysis (COA) documenting all specifications is provided with every shipment.

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 the container sealed under an inert atmosphere if specified and away from incompatible materials such as strong reducing agents.
