Quality Control

Every batch of this cyanine dye is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure it meets the high-purity standards required for sensitive applications. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes data for identity, purity (HPLC), absorbance/fluorescence spectra, and moisture content. Our quality protocols are designed to support GMP/GLP-compliant research and production environments.

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); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect performance and stability.
