Quality Control

Our Cyanin Chloride is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR for structural confirmation, and spectrophotometric analysis to ensure it meets precise specifications for critical applications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from incompatible materials. Due to its light-sensitive nature, containers should be amber-colored or stored in opaque secondary packaging.
