Quality Control

Our 3,3'-Diethyloxadicarbocyanine Iodide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for absorbance/fluorescence verification, and identity confirmation via IR and NMR. We provide a detailed Certificate of Analysis (COA) with every 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). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccant or inert atmosphere conditions.
