Quality Control

Our Diethyldicarbocyanine Iodide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for absorbance verification, and identity confirmation via IR and NMR. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment away from direct light exposure to maintain stability and purity.
