Quality Control

Our 3,3'-Dihexylthiacarbocyanine Iodide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification, spectrophotometry for absorbance/fluorescence characterization, and identity confirmation via IR and NMR. We provide a Certificate of Analysis (COA) with every shipment, detailing all critical specifications to ensure batch-to-batch consistency and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as specified on the label or COA. This product is hygroscopic (moisture-sensitive) and light-sensitive (store away from light); therefore, containers must be kept sealed under inert atmosphere (e.g., argon or nitrogen) when not in use to prevent degradation.
