Quality Control

Our 1,1'-Diethyl-4,4'-Quinocyanine Bromide is produced under stringent conditions to ensure batch-to-batch consistency and high purity, suitable for research and development applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to ISO 9001 quality management principles, and our analytical methods, including HPLC and spectroscopic analysis, are validated to provide reliable specifications for our global clientele.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a desiccated environment to prevent degradation. For long-term stability, consider storage under an inert atmosphere.
