Quality Control

Our production of this specialty cyanine dye adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Every lot is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing purity, absorbance maxima, and impurity profiles is provided with each shipment to support your R&D and quality assurance processes.

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 compound is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccant or inert atmosphere.
