Quality Control

Our production of this cyanine dye adheres to strict quality management protocols to ensure batch-to-batch consistency and high performance in sensitive optical applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and relevant physical properties 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). This material is hygroscopic (moisture-sensitive) and light-sensitive; ensure the container is kept sealed in a dry environment to prevent degradation and absorption of moisture.
