Quality Control

Our production of this advanced cyanine dye adheres to strict quality management protocols, ensuring batch-to-batch consistency and high chemical purity. Each lot is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your R&D and quality assurance 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 material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
